Ingredients:
1 4-4.5 pound beef brisket
1/2 teaspoon salt
1/2 teaspoon garlic powder
1/2 teaspoon white pepper
1/4 teaspoon red pepper
8 oz sour cream
2 Tablespoons horseradish
Instructions:
Begin the day before serving. Place brisket in a large, flat baking pan with the fat side down. Mix together salt, garlic powder, white and red peppers and sprinkle over the meat. Cream together the sour cream and horseradish and coat the meat with this mixture. Let marinade overnight. When ready to cook, preheat oven to 300 degrees. Turn brisket over in pan so that fat side is up. Cover pan with foil. Bake four hours. Slice thin across the grain and serve.
