1/4 cup vegetable oil
1/2 medium white onion, chopped
2 cloves garlic, chopped
1 cup ketchup
1/2 cup cider vinegar
1/4 cup soy sauce
1/4 cup dark brown sugar
2 Tbsp. Worcestershire sauce
2 tsp. dry mustard
1 tsp. celery seed
In a medium-sized saucepan, heat the oil and sauté the onion and garlic for 5 minutes. Add the remaining ingredients and simmer, stirring frequently, until slightly thickened, about 10 minutes. Cool the marinade before using. Makes 2 cups; enough for 6 pounds of beef, chicken or pork.
