How To Cook Perfect Brisket
1. Trim Fat
Remove any large or hard patches of fat from the flat (the meat that runs along the entire brisket) so the rub will adhere to the meat and create a nice bark during cooking.
2. Remove Hard Fat
Next, remove the hard fat heel that sits between the point and the flat. This fat should be removed because it will not render during cooking.
3. Trim and Shape
Continue trimming excess fat from the brisket, as well as any fat that appears discolored. Trim from both sides of the brisket, and square off the edges. This will help ensure an even cook.
4. Check the Fat Cap and Finish Trimming
Check the side with the fat cap (the thick layer of white fat, common in pastured animals, that covers one side of the meat) for any hard or large patches of fat. Trim the fat cap to about ¼ inch of fat throughout. The finished brisket should be nice and square, with even fat and marbling. (You can also ask your butcher to trim the brisket for you.)
5. Season the Meat
Brush or rub the entire brisket with Worcestershire sauce so the seasoning will stick. Once the brisket is moist, apply a heavy coating of rub, and let the brisket sit in the refrigerator for a minimum of 4 hours before placing it on the smoker.
6. Smoke It and Check the Bark
Let the brisket sit at room temp 1 hour, then place it, fat side down, on the top food grate, and close the smoker. Smoke 5 hours or until thermometer inserted into the center of the brisket, where the point and flat meet, registers 165°. At this point, the brisket should have a rich, dark mahogany color and will no longer take on any smoke while cooking.
7. Remove and Wrap
Remove the brisket from the smoker, and wrap it tightly in wax-free butcher paper. Return it to the smoker, and cook 3 to 5 more hours, checking temperature hourly until thermometer inserted into the center of the brisket registers 200°.
8. Rest and Slice
Remove the brisket from the smoker, and allow it to rest (wrapped) for 2 hours, preferably in an empty cooler or insulated food storage container. Unwrap and place brisket on a cutting board, reserving drippings in butcher paper (to mix into your barbecue sauce). Cut the meat across the grain into ¼-inch-thick slices.
