Step 1
Mix cola, tomato sauce, tomato paste, Worcestershire sauce, brown sugar, molasses, cider vinegar, butter, balsamic vinegar, steak sauce, and mustard together in a large saucepan over low heat. Stir in chili powder, savory, onion powder, garlic salt, and hot pepper sauce until well blended. Cook, stirring occasionally, until sauce is thick enough to coat the back of a metal spoon, 10 to 15 minutes.
