I want to make my first attempt at making some BBQ sauce. I thought it would be fun to make it entirely from scratch with fresh tomatoes. While looking at recipes, it seems most are made from canned puree or ketchup. I was just wondering about the differences between all of these option. Is there any benefit other than the time or amount of work it takes to make the sauce? I imagine that ketchup makes for a bit of a tangy sauce since it already has other ingredients in it. Thoughts?
