Texas Barbecue Brisket Recipe

1 (5-pound) brisket of beef
1 teaspoon salt
Freshly ground pepper to taste
1 large onion, chopped
2 celery stalks, chopped
1 cup chili sauce
1 cup water
1/4 cup chopped parsley
1 (10-ounce) bottle of beer

Preheat oven to 325 F. Remove most of the fat from the brisket and wash and dry. Sprinkle with salt and pepper. Place the meat, fat side up, in a heavy casserole and cover with the onion, celery, chili sauce, water and parsley. Bake, uncovered, in preheated oven for 1 hour. Pour the beer over the beef and bake, covered, 3 more hours or until tender. Cool to room temperature, refrigerate, skim off the fat, slice and reheat in the drippings.
