This does taste similar to the off brand catsups. After adding the brown sugar and vinegar, it still tastes like tomato sauce. It also turned out a little runny. (Crushed tomatoes instead of sauce might help to thicken it.) I would not count on this for a ketchup substitute. After tasting it, since I didn't like it, I thought I would simmer it to thicken and also added a dash of Lawry's season salt and onion powder which helped get rid of some of the tomato sauce taste. I will use it to make some homemade bbq sauce to keep it from being a total loss.
