Here is something you can change around to make work for you. I have made it sugar free, using brown slenda or regular and some molassas.
Red Barby Sauce
1 ½ cup Ketchup
1 8oz. can Tomato Sauce
½ cup water
½ cup brown sugar
½ cup red wine vinegar
1/3 cup Worcestershire sauce
2 T soy sauce
½ t each Black Pepper, dry mustard, garlic powder, onion powder, dried oregano, dried basil crushed red pepper
¼ t allspice
Mix all together boil 3-4 minutes, simmer 10-30 minutes until desired consistency.
I may have even bought spice packets to make your own ketchup thus controling what goes in it.
