While visiting a friend we found an old recipe book of her Mom's with a recipe for tomato butter. Since I bought a 1/2 bushel of canning tomatoes I'll probably try this recipe with some of them. It directs you to "grind" tomatoes & onions and combine with brown sugar, vinegar and spices (cinnamon, allspice & ?) then simmer until thick. I've had storebought tomato marmalade and wondered if this will come out similar.
