I put only a tablespoon or so. I don't remember if that's part of the actual recipe, but I know my mom always puts brown sugar in her sauce. I made my sauce for my Christmas party and everyone loved it. My mom gushed over it, lol. I had to give her my recipe for a change, haha.I like Muir Glen canned tomatoes and I only use salt pepper and garlic. I cannot have any sugar in my tomato sauce which is odd considering my love of sugar.
