MIKE'S ORIGINAL is the sauce we use daily in their restaurant, with a nod to all of the barbecue regions -- it contains ketchup, vinegar, and mustard, and it's a savory sauce, not sweet.
Ingredients: Ketchup (tomato concentrate from vine-ripened tomatoes, cane sugar, distilled vinegar, salt, less than 2% of onion powder, spice, natural flavors), Mustard (distilled vinegar, water, #1 grade mustard seed, salt, termeric, paprika, spice, natural flavors and garlic powder), Apple Cider Vinegar, Sugar, Brown Sugar, Worcestershire Sauce (distilled white vinegar, anchovies, garlic, molasses, onions, salt, sugar, water, chili pepper extract, cloves, natural flavorings, tamarind extract), Lemon Juice, Water, and Natural Spices
