Recipe by Karen From Colorado

Nothing tastes better then homemade ketchup on a grilled burger. With all the gardening plans coming up, I thought this would be a good time to post this recipe. Very easy to do.

My husband is a ketchup freak - puts it on everything, so I thought I'd try this. Very, very good. We had it on hamburgers first and it was a winner. I think it would be easy to modify it to make it a little hotter, less sweet, however you like your ketchup. We thought this was perfect. By the way, I used plum tomatoes and just doubled the number and it was still great.
