I am working on making my own red sauce. I have started with 1 1/2 cups ketchup, 1/2 cup white vinegar, 1/2 cup acv, brown sugar, spices. I heated up until it simmered and took it off. All i taste is ketchup on the front end and tartness of vinegar on the back. I tried adding more sugar but still over whelming ketchup. It seems like this is always the issue when i try making my own red sauce. Am i missing something? Is there something that can be added that would help?
