I'm not a fan of sugar of any kind in spaghetti sauce, but I understand that in Europe they tend to use a dash of cinnamon instead of sugar. Interesting.

Whatever you wind up doing, do it sooner than later. The heat waves in California killed off a lot of this year's tomato crop intended for the canned goods. I'm probably going to just go get #10 cans [the size of my head] to get the family through to next spring.
