1–1/2 teaspoons hot pepper sauce (I used 2 teaspoons)
1 teaspoon prepared horseradish
1 teaspoon salt
1/2 teaspoon garlic powder
2 teaspoons liquid smoke (optional)
2 beef briskets totaling 5-6 pounds or one large 6 pound beef brisket (if you can find it)
Instructions
Saute onion and butter in a heavy saucepan until tender. Add the next nine ingredients; bring to a boil. Reduce the heat; simmer, uncovered for 30 minutes until reduced to about 6 cups.
Place the brisket in a roasting pan. Add 3 cups of sauce. Cover and bake at 250 degrees for 4-1/2 hours for two smaller briskets or until the meat pulls apart easily, basting occasionally. If you use one large 6 pound brisket bake at 325 degrees for 5-1/2 hours, covered. Skim any fat. Remove brisket and let rest for 15 minutes. Thinly slice the beef and pour remaining sauce from the pan and reserved sauce over the beef. Or throw the thinly sliced beef back into the roasting pan with the cooking sauce and add the sauce you reserved and completely coat the meat, then plate it up. It will be so saucy and so good.
I haven’t tried it but I bet this would do well in a slow cooker.
