1 (4 to 6 pound) fresh beef brisket, well trimmed
1 cup barbecue sauce (your favorite)
1/4 cup Worcestershire sauce
1/4 cup Liquid Smoke
1 teaspoon garlic powder
2 teaspoons celery salt
2 teaspoons lemon pepper
1 teaspoon salt
1 cup chopped onion
1/2 cup water
Preheat oven to 275 degrees F.
In a large Pyrex baking dish, thoroughly mix all ingredients for sauce. Put the brisket in the baking dish, and turn it over once to coat it with the sauce. Seal the dish well with heavy-duty aluminum foil.
Bake at 275 degrees F for 5 to 6 hours.
Remove brisket from oven and allow to stand for one hour before slicing.
Slice across the grain, and serve with sauce.
Makes 8 to 10 servings.
