Brisket is cut from the breast section of a side of beef. Each beef carcass renders only two whole briskets.
According to the USDA Institutional Meat Purchasing Standard (IMPS), a beef brisket as it's cut from a side of beef "includes the anterior end of the sternum bones, the deep pectoral, and the supraspinatus muscle. Evidence of the cartilaginous juncture of the 1st rib and the sternum and the cross section of 4 rib bones shall be present." You'll never find this bone-in brisket in the meat department of a U.S. supermarket.
The whole brisket you'll buy for barbecue is what the IMPS calls "beef brisket, deckle-off, boneless." The IMPS defines it as follows: "All bones and cartilage shall be removed. The deckle (hard fat and intercostal meat on the inside surface) shall be removed at the natural seam exposing the lean surface of the deep pectoral muscle. The inside lean surface shall be trimmed practically free of fat." The word "intercostal" refers to meat between the rib bones.
The deep pectoral muscle (the "inside lean surface") is commonly referred to as the brisket flat, while the supraspinatus muscle is commonly known as the brisket point.
Contrary to popular belief, the deckle is not the same thing as the brisket point. Rather, it's the fat and muscle that attach the brisket flat to the rib cage.
The flat is just that: Sort of a flat, rectangular piece of meat that makes up the majority of the whole brisket. This is the portion that is sliced across the grain and served on a plate or in a sandwich. You've probably seen the flat in the meat case at the supermarket, separated from the point and with most fat removed, ready for braising in the oven.
The point is a lump of meat that partially overlaps one end of the flat. It is quite fatty on its surface as well as within the meat. It also contains a lot of connective tissue between the meat fibers. It can be sliced, but its loose texture after cooking makes it a better choice for chopped brisket sandwiches or burnt ends.
The flat and point are separated by a very thick vein of fat running between them. This fat extends over the entire surface of the flat, becoming thinner at the end opposite the point. This layer of fat is sometimes referred to as the "fat cap". Thick fat may also wrap around one edge of the brisket flat, especially near the point.
From an anatomical perspective, the brisket flat is the "deepest" portion of meat and is attached to the rib cage, while the brisket point sits on top of the flat and is nearest the surface.
Still confused about what's the flat and what's the point? Here's an easy way to orient yourself to a whole brisket: One side of the brisket has a large area with essentially no fat on it. With the fat-free side facing down, the flat is on the bottom and the point is facing up at the high end of the brisket.
The grain of the meat in the flat and point run almost perpendicular to each another. As a result, the two sections should be separated after cooking and dealt with separately.
There are several considerations when selecting a brisket for barbecuing.
Quality Grade: Buy USDA Choice
Choose a USDA Choice grade brisket, if available. Look for the USDA Choice shield on the package, as shown in Photo 1. A Choice grade brisket should have slightly more marbling (intramuscular fat) than a USDA Select grade brisket. Having said that, I have cooked many USDA Select grade briskets with great success, but I prefer USDA Choice when I can get it.
Some people that participate in barbecue competitions seek out USDA Prime grade briskets, the highest quality grade available. Prime briskets are difficult to find, but those who use them report excellent results.
Some beef producers "brand" their beef products—not with a red-hot
branding iron, but with fancy marketing names. Examples of successful
branded beef include Certified Angus Beef (CAB), Meyer Natural Angus
Beef, and IBP Chairman's Reserve Certified Premium Beef. Pretty much
any meat that has a fancy name attached to it is a branded beef
I've cooked both branded and non-branded briskets, and I can't tell them apart. If you have a choice between branded and non-branded briskets at roughly the same price, consider going with the branded product, as long as it has that all-important USDA Prime or USDA Choice grade shield on the package. Without that shield, you have no guarantee of quality, no matter what the butcher tries to tell you.
Whole, Untrimmed Brisket In Cryovac
Buy a whole, untrimmed brisket still in the Cryovac packaging. This is
referred to as "packer cut" or "packer trimmed" brisket—my German butcher
Mark Bubert calls it "brisket for Texas barbecue." Buying an untrimmed
brisket allows you to trim it just the way you like, and all that fat
will keep the meat moist during cooking. Photos 2-3 show what a whole
brisket in Cryovac looks like.
Large brisket flats with the fat cap intact can be barbecued successfully, and some folks prefer this to whole brisket, as there is less waste.
If you'd like to get more familiar with a whole brisket, take control of this Virtual Brisket.Weight
Whole, untrimmed briskets weigh 8-16 pounds. Something in the 10-12 pound range is your best bet and will fit on either WSM cooking grate.
Large brisket flats with the fat cap intact weigh 6-7 pounds.
Briskets larger than 12 pounds can be "shoehorned" between the handles on the top cooking grate, or a portion of the flat section can be folded under itself. After several hours of cooking, the brisket will shrink and fit more comfortably on the grate.
If you're cooking a monster brisket on the bottom cooking grate and it extends beyond the edge of the water pan, you may want to wrap some foil around each end of the brisket. This protects it from the blast of heat coming up from around the water pan. Once the brisket shrinks and no longer sticks out past the edge of the pan, you can remove the foil.
White, Hard Fat
wisdom in barbecue circles is to choose a brisket covered in white,
hard fat. This indicates that the animal was fattened on grain at
the feedlot during the final weeks before slaughter. Fat that trends
toward yellow in color is an indication of grass feeding and is
thought to be less desirable for barbecued brisket—although
attitudes may change as grass-fed beef becomes more popular in the
Flat With Even Thickness
Try to choose a brisket that has a flat section of even thickness. Most flats tend to narrow a bit toward one edge, and this is normal—but avoid those that taper off to a very thin edge. Even thickness helps promote even cooking and provides uniform slices. Again, this can be difficult to judge through the Cryovac packaging, and may be a moot point if you don't have many briskets from which to choose.
people believe that the flexibility of a brisket is an indication of its
tenderness. Frankly, I don't know how to evaluate this when a
brisket is still in Cryovac. I don't know about you,
but my butcher won't let me unwrap meat and handle it before
purchase. So I don't know what to make of this claim.
There are some folks who do nothing more than remove the brisket from the Cryovac, pat it dry with paper towels, apply a favorite rub, and throw the brisket into the cooker. If this works for you, go for it.
I had never seen a whole brisket until I attended the Paul Kirk Pitmaster Class in 1997, and the way he taught us to prep a brisket in that class is the way I've been doing it ever since.
Chef Paul's main point was this: It makes no sense to leave all of the fat on the brisket. Smoke and rub won't penetrate it. It will take more time and fuel to cook the brisket with all the fat intact. And in the end, you're not going to eat the fat—you're going to cut it away and discard it.
So, Chef Paul's approach was to cut away some of the thickest areas of fat on the brisket and to trim the fat cap over the flat to 1/8" to 1/4". This leaves enough fat to keep the brisket moist during cooking.
Before going any further, I must point out that every brisket is unique—no two are identical! I continue to be amazed at the variation from one brisket to the next in terms of size, shape, amount of fat, and the relationship between the flat and point sections. So don't be surprised if your brisket is longer, shorter, skinnier, fatter, taller, or different in some way from those shown in the photos below. I should also point out that a couple of different briskets are pictured below, which explains some of the differences you'll see between photos.
One last note: It's an exercise in futility to try trimming a brisket with a knife that's not up to the task. You need a very large, sharp knife. Don't try this with a paring knife, a utility knife, or any knife that is dull. A butcher's knife, like the one shown in Photo 7 below, does a great job, but a large, very sharp chef's knife will do.
Remove Brisket From The Cryovac
Remove the brisket from the Cryovac packaging. Pat dry with paper towels. Place on a large cutting board with the point facing up. Remember, the brisket has one side with a large, relatively fat-free area—if you place that side facing down, then the point will be facing up.
Trim Thick Areas Of Fat Around The Point
Most briskets have extremely thick areas of fat on top of and around the point section (Photo 6), as well as a thick edge of fat running down one side of the flat section (Photo 7). Trim away most of this fat as best you can. Remember, the goal is to remove excess fat while still leaving a 1/4" layer to protect the meat below.
Admittedly, it takes some time and experience to judge this, and there's really no harm if you leave too much fat. You also don't have to freak out if you cut a little too deep and strike red meat! Just back off on the knife and don't cut so deep. Take your time and remove what make sense to you, without cutting so close that you're exposing the meat.
You will notice a very thick vein of fat running between the point and the flat sections. Some folks just trim fat from the surface of this vein, without actually cutting into the vein itself. I like to cut a V-shaped chunk of fat from this vein. You can be pretty aggressive in removing fat from this area, but if you keep cutting and cutting, you'll end up almost separating the two sections! In fact, in Photo 8, I think I was a bit too aggressive and should have left more fat.
Trim Fat From The Flat
Now turn your attention to the large expanse of fat covering the brisket flat. Trim the surface fat, leaving a 1/8" to 1/4" layer. By running your fingers over the surface, you'll get a feel for where the thickest areas are located. Just go slow and trim carefully, backing off on the knife if you hit red meat. Again, this takes some practice, so don't beat yourself up if you shave a spot a little too close. There's no harm done if you leave a little too much fat.
Photos 9-10 show the same brisket flat before and after trimming. Notice that toward the end of the flat, I only had to trim fat from the right side; the left side was already in the 1/8-1/4" range.
As you move down the flat away from the point, the fat becomes less hard and more spongy, making it more difficult to cut. This is where a sharp butcher's knife really helps.
Turn & Trim The Other Side
Turn the brisket over. You should be looking at a large expanse of flat that needs little trimming, if any at all.
There may still be some significant fat around the bottom side of the point and in the vein between the two sections. In fact, the vein of fat may appear more pronounced from this side than from the other side. Trim away what makes sense to you.
In Photo 11, you'll notice that I made another V-shaped cut into the vein, leaving behind a more appropriate amount of fat this time.
The End Result
Here's how the brisket may look after trimming.
Photo 12 shows the fat side facing up, with a 1/8" to 1/4" layer of fat covering the whole surface. On this brisket, a thick edge of fat ran down the right side of the brisket, and I trimmed most of it away.
Photo 13 shows the same brisket flipped over, with the lean surface of the flat facing up. I trimmed much of the fat from the vein between the point and flat.
Marking The Brisket
Sometimes it can be difficult to determine which way the grain is running in the flat after cooking. In the Pitmaster Class, Paul Kirk suggests that you trim a small corner of meat from the end of the flat section, perpendicular to the grain of the meat. Use that edge as a guide for slicing across the grain after cooking.
As I suggest later in this topic, if you remove the point from the flat section before slicing the flat, the grain becomes well exposed and you won't have much difficulty determining which direction the grain runs.
There are some hardcore fanatics in the Lone Star State that just apply salt and pepper to a brisket and smoke it. They let the natural flavor of the meat and smoke do all the talking. Most people, however, prefer to season a brisket with something a bit more complex.
After trimming a brisket, you can use either a dry rub or a marinade to season the meat. You can apply the rub and put the meat into the cooker immediately, but I prefer to apply rub, then wrap in plastic wrap and refrigerate overnight. I don't have any illusions about the rub penetrating the meat, because it doesn't, at least not deeply. However, it does form a moist layer of seasoning that adheres well during cooking. I also usually apply a bit more rub before putting the meat in the cooker. As in the Pork Butt - Slathered With Mustard & Rub article, you can apply a thin coat of mustard to a brisket before sprinkling on the rub, if you like.
A marinade is a liquid concoction in which a brisket is soaked, usually overnight. Typically, it's a mix of a dry rub with some flavorful liquid such as beer or soda pop. Again, don't be deceived into thinking that a marinade somehow penetrates the meat to its core, because it doesn't. It only affects perhaps the outer 1/8" of meat. Nor does a marinade tenderize meat deep inside. Marinades that contain an acid, like vinegar, may have an affect on the surface of meat, but if you're not careful, it will just make the surface sort of mushy. So think of a marinade only as a method for adding flavor to the outside of meat.
You'll find lots of dry rub and marinade recipes in the Rubs & Marinades forum on The Virtual Weber Bulletin Board. In Brisket - Wet Rub, I used a paste on a brisket, which is sort of a wet rub...or a really thick marinade.
There are two schools of thought on this point. Some recipes, including some on this website, suggest that you allow a brisket to sit at room temperature for up to two hours before cooking. This helps to minimize the difference in temperature between the meat and the cooker.
Why is this important? Some barbecue experts say that cold meat can be fouled by creosote that results from a poorly managed fire, especially in wood-burning cookers. The result is a brisket with a bitter taste. This isn't much of a concern in the WSM as long as the top vent is fully open at all times. And of course, the WSM is charcoal-fired, not wood-fired. Others say that a brisket at room temperature takes less time and fuel to cook than a cold one, but I'm not sure this is much of an issue, either.
In the other school of thought, we have those who believe it's best to take meat straight from the refrigerator and put it into the cooker. Their theory is that the smoke ring, that pinkish/purple color that forms beneath the surface of the brisket, is formed only while the meat is below 140°F. By starting with a colder piece of meat, it spends more time below 140°F in the cooker, resulting in a stronger smoke ring.
I've cooked briskets both ways, and I'm not sure I can tell a difference either way. Lately, my habit has been to take the brisket from the refrigerator and place it directly in the cooker. I've not gotten out a measuring tape to see what affect, if any, this has on the formation of the smoke ring, nor have I noticed any bitter flavor to the meat.
Frankly, I think meat temperature is more of an issue with grilled meats that cook quickly over high heat than it is for large cuts like brisket that barbecue for many hours.
In his book On Food And Cooking, author Harold McGee says that meat is composed of three tissue types: muscle fiber, connective tissue, and fat. Connective tissue consists of the proteins collagen, elastin, and reticulin. Collectively, these proteins bind the muscle fibers together and help connect muscles to bone—McGee calls it "the physical harness of the muscles."
Brisket has an abundance of connective tissue, as do most muscles that work very hard. It's this connective tissue that makes brisket such a tough cut of meat. The good news is that muscles that work hard tend to be more flavorful than those that don't work hard.
According to McGee, connective tissues made of elastin and reticulin don't break down during cooking, but collagen turns into soft gelatin. It is this conversion from collagen to gelatin that renders the tough old brisket into the tender barbecue we enjoy so much.
In the book How To Cook Meat, authors Chris Schlesinger and John Willoughby say that tough cuts of meat must be "cooked through doneness to tenderness." In other words, you don't stop cooking a brisket when it reaches the internal "done" temperature we associate with tender cuts of beef like a Porterhouse steak or even a tri-tip roast. A brisket is not edible if cooked to 125°F or even 175°F.
In order to be tender, a brisket must be cooked to an internal temperature of 180-205°. The reason for this, according to McGee, is that the conversion of collagen to gelatin doesn't even begin until meat reaches an internal temperature of 140°F, and is most efficient as internal temps approach 212°F. "Low and slow" barbecuing at 225-250°F is ideal to facilitate this conversion, providing gentle heat over many hours, allowing the collagen to make its transition into gelatin. While some moisture will be driven out of the brisket as it reaches these high internal temps, the gelatin makes up for it and keeps the meat moist. Of course, the fat layer on the brisket also helps maintain moisture in the meat during cooking, too.
Barbecue experts with years of cooking experience say a brisket is done when it's "fork tender", meaning that a fork or a probe thermometer goes in and out of the meat with little resistance. The problem is that both a properly cooked brisket and an overcooked one will both be "fork tender". For most folks like you and me, it's best to rely on internal meat temperature to determine when a brisket is properly cooked.
What most everyone does agree on is that a properly cooked slice of brisket should pull apart easily, while still maintaining good texture. An overcooked slice will fall apart when picked up.
188°F and 190°F seem to be the most popular target temps. I cook brisket to a variety of internal temps, depending on the method I use to cook them. When I barbecue a brisket entirely in the WSM, like in Brisket - Midnight Cook, I cook to an internal temp of 185-190°F. In this temperature range, the flat will be fork-tender and the slices cut from the flat will hold together.
When I use the method described in Brisket - Smoked & Oven Finished, I may take the brisket as high as 205°F internal. At this higher temp, the flat will be extremely tender and may have to be sliced a little thicker to hold together. Some would say that a brisket cooked to this temp is on the verge of being overcooked. In the end, it's up to you to determine what you like.
How long will it take to cook brisket to 180-205°F? As a rough estimate, assuming a cooker temp of 225-250°F, figure 1 hour to 1 hour 15 minutes per pound for a whole, packer brisket weighing 8-12 pounds after trimming any excess fat. Remember, this is only an estimate—it may take more or less time, depending on the thickness of the brisket, the amount of connective tissue that needs to be converted to gelatin, the temperature of the cooker, weather conditions, and the number of times you open the cooker for turning and basting.
I get confusing temperature readings in the point end of a brisket, probably because of all the fat and connective tissue. Your best bet is to measure the internal temp in the flat section. Insert an instant-read or probe thermometer into the middle of the flat from the side of the brisket—not from the top. This picture shows how to place a Polder probe into a brisket.
Some people cook briskets fat-side up, while others cook fat-side down. Some people turn briskets during cooking, others don't. When I first learned how to cook a brisket in 1997, I was taught to start the brisket fat-side up and to turn and baste it as described below in Turning & Basting. However, during 2004 more and more barbecue competitors began singing the praises of cooking brisket fat-side down and not turning it at all—and sometimes not even basting it.
Proponents of fat-side up say it allows the rendered fat to "baste" the brisket flat during cooking. In his School of Pitmasters Class, Paul Kirk suggests that you start a brisket fat-side up and then turn the meat "at the halftimes" to promote even cooking, and that's what I've done for many brisket cooks. (The halftime process is described below in Turning & Basting.)
Proponents of fat-side down say that the fat layer shields the brisket flat from the direct heat coming up from the bottom of the cooker, preventing it from drying out. They will cook fat-side down the entire time without turning or basting the meat even once.
As mentioned in the previous section, not everyone agrees upon the need to turn and/or baste a brisket during cooking, but if you decide to do it, consider using the "halftimes" method described below.
Assuming a 10-12 pound whole brisket and 1-1/2 hours of cooking time per pound as a guideline, calculate how long it will take to cook the brisket. For example, a 12 pound brisket will take approximately 18 hours to cook. Divide this time in half. So, the first time to turn and baste the brisket is at this halfway point: 9 hours. If you baste sooner than the halfway point, the rub won't have a chance to set up on the surface of the meat and you'll end up washing away much of it.
Basting helps keep the meat moist and adds a little flavor to the surface of the meat. Baste one side of the brisket, then turn it over and end-for-end and baste the other side. You can baste with any flavorful liquid you like. It might be apple juice applied with a spray bottle or a complex concoction applied with a cotton mop. Again, you'll find lots of ideas in the Recipe Forums on The Virtual Weber Bulletin Board.
Now, divide the remaining time in half. In our example, the next time to turn and baste the meat will be in 4-1/2 hours. Repeat this process until about the last hour of cooking, then stop turning and basting.
Remember, every time the cooker is opened, it loses temperature, so be quick and efficient when turning and basting.
It's common for a brisket to reach a temperature plateau during cooking—a point at which the internal temperature stops rising and stalls, sometimes for several hours. It happens when the brisket reaches 160-170°F, when the meat fibers are contracting and squeezing moisture out to the surface of the brisket. It takes quite a bit of time and heat energy to evaporate that moisture, and the internal meat temp will not move out of the stall until that moisture is evaporated
With some patience and a 225-250°F cooker temperature, the brisket will eventually move beyond the plateau and the meat temperature shall rise again. If you want to shorten the length of the stall, just kick the cooker up to 275°F. Or, when the brisket reaches 160-175°F, wrap it in foil and finish it in a 300°F cooker or oven, like in the Brisket - Smoked & Oven Finished article.
As with any large roast, it's important to let a brisket rest for at least 30 minutes before slicing so the juices inside the meat have a chance to redistribute. I'll never forget the first time I cut into a brisket as it came right out of the cooker—it gushed liquid all over the cutting board and ended up being quite dry! You can read more about the science behind this in Letting Meat Rest After Cooking.
At a minimum, place the brisket on a rimmed baking pan, cover loosely with foil, and let rest 30 minutes before slicing.
For even better results, wrap the brisket with aluminum foil, place it fat-side up in an empty ice chest, and let rest for 1-2 hours (Photo 16). The meat will continue to cook for a little while because of carry-over heat, making the meat even more tender. More importantly, the extended rest results in moister meat, and the collected juices inside the foil will soften any tough crust on the brisket flat.
Some folks will even pour a little beef broth into the foil package with the brisket before sealing it tightly for the extended rest, again to help promote moister meat.
Whatever you do, save the juices that have accumulated in the foil (Photo 17). Separate the fat and use the remainder to moisten leftover brisket the next day, or use it as an ingredient in homemade barbecue sauce.
After resting, it's common to separate the point from the flat and deal with each section separately.
Photo 18 shows what happens when you slice a whole brisket without separating point from flat. In the photo, the point is on the top, the flat is on the bottom, and the grain of the meat runs in different directions in each section. If you slice the whole brisket so that the flat is cut across the grain as shown in the photo, the point is not cut across the grain and it ends up being a bit chewy. That's why you want to separate the two sections and slice the flat and either slice, chop, or make burnt ends with the point.
Here's how to break-down a whole, cooked brisket.
Separate The Point From The Flat
The dark, almost burned looking piece of meat in Photo 19 is, in fact, a properly cooked brisket. Don't be surprised if your brisket turns out looking like the one shown here.
Start by separating the point from the flat. After the brisket has cooked, the demarcation between these two sections becomes fairly clear. Often times, you can take hold of the point section, move it back and forth, and see where the thick vein of fat is that separates the two sections.
Using a sharp knife, cut through that thick vein of fat to separate the two pieces. Some people find that scraping the excess fat from the flat section first helps to reveal the vein of fat between the two sections more clearly; I don't recommend that you do this. You've worked too hard to develop a crust on the brisket, and that fat you're scraping off is flavor.
Photo 20 shows how the two pieces look after being separated. The flat is on the left and the point on the right. This particular brisket has an enormous point, almost as big as the flat, which is quite unusual. The point on your brisket will most likely be smaller.
Slice The Flat
You do want to scrape the unattractive fat from the flat section where it was connected to the point. Determine the direction of the grain of the meat, then cut across the grain into 1/4" slices. If the meat seems a bit tough, slice it thinner; if fall-apart tender, slice it up to 1/2" thick.
Photo 21 shows how the slices will look. A 12" slicing knife works best for a large brisket flat. If the brisket is a lot wider than your knife, cut the brisket down the center with the grain, then cut shorter slices across the grain from each half.
Sliced brisket dries out real quick. Don't let the pieces flop around like I did in Photo 21—keep them together as you slice them. Slice only as much brisket as you're going to eat right away. To retain moisture, keep the remainder as a whole chunk and slice it later.
Slice Or Chop The Point
Trim the excess fat from the point section and either slice it across the grain or chop the meat. I don't care for the texture of sliced point very much. My preference is to shred the meat and serve it on a plate or in a sandwich.
To shred the point, hold a serrated knife across the grain and push the knife away from you at an angle down through the meat. You're not trying to cut a clean slice—you want to tear shreds from the soft meat. Weed out any bits of excess fat and connective tissue that did not break down during cooking. Add to the shredded meat any cutting board leftovers from slicing the flat section, then chop through the meat a few times with a chef's knife to cut up any large pieces.
Photo 22 shows slices from the flat on the left and chopped meat from the point on the right.
The Texas Turn
Down in Texas, some pitmasters don't like to separate the flat and point sections. Instead, they start by slicing the brisket flat across the grain, and just as they hit the point section, they turn the brisket 90° and slice across the grain of the point. This results in a slice of meat containing both point and flat, where the point is cut precisely across the grain, but the flat is cut at an angle across the grain.
Traditionally, burnt ends sold in restaurants were the dry edges and leftover bits and pieces of the brisket flat after slicing, mixed with barbecue sauce. These morsels were highly prized for their intense, smoky flavor.
Today, famous barbecue joints like Arthur Bryant's in Kansas City can't meet the demand for burnt ends using leftover bits, so they make a facsimile by cubing fully cooked brisket flats, placing the cubes in a pan and smoking them for a couple of hours, then adding sauce and smoking for a couple more hours.
Another approach for making burnt ends is to separate the point section from the flat section after the flat is done, then return the point to the cooker for an additional 4 hours. Cut the point into cubes, mix with just a little barbecue sauce, and enjoy!
See the Burnt Ends article for more details and photos of this process.
When you take into account the trimming of the brisket before and after cooking, plus the shrinkage that occurs during cooking, don't be surprised if you end up with a 50% yield of edible meat from a whole, untrimmed brisket. That means 6 pounds of edible meat from a 12 pound brisket. Depending on the brisket and the internal temp you cook it to, it may be as low as 40% or as high as 60%.
If you're cooking brisket for a party, figure 4-5 ounces of meat per sandwich or 6 ounces of sliced meat on a plate (8 ounces for hearty eaters). Using a 40% yield, just to be safe, a 12 pound brisket yields 19 4-ounce sandwiches or almost 13 6-ounce plate servings.
There's a good chance you'll end up with leftover brisket. See Holding, Storing & Reheating Barbecued Meats for tips on how to freeze and reheat the leftovers.
