Home made ketchup anyone?

My friend had so many tomatoes this year, so we decided to try and make homemade ketchup, that way our kids didn't have to eat all the sugar in the store brands. It was so fun, we had over four baskets full of tomatoes. But in the end we only made 12 jars total. Was it worth it? I don't know since it took all day. But it was sure fun and adventurous.
