Last year I tried to make homemade ketchup and I did can it but it was not good. This year I wanted to try it again but I did not want to waste my own tomatoes in case it did not turn out again. So, I bought this 6 lb. can of diced tomatoes from Sam's Club for $2.53. Hey - they were Red Gold and were at least processed in Indiana.
I used Mrs. Wages ketchup mix. It tasted like . . . ketchup! Success, of course next year I will try it with my own tomatoes (and maybe I might do it again this year), but I need to wait to make sure my family will like it. We are big ketchup fans here.
With the 6 lbs. of diced tomatoes I ended up with exactly 12 half pints (jelly jar size) of ketchup.
Here is the numbers - I paid $1.50 for Mrs. Wages mix and $2.53 for the tomatoes. I did have to add tomato paste, sugar and vinegar all totaling about $0.75. It is about $0.40 per half pint. Of course, if I would have used my own tomatoes it would have been about $0.20 per half pint - definitely worth it!
What are you canning?
