How to Replace Fresh Tomatoes with Canned Tomatoes

If your cooking needs whole canned tomatoes, you can use whole fresh tomatoes if you have them. Fresh tomatoes that you peeled, cooked, and blended yourself can be used in place of bottled tomato puree. While you can boil and dry your fresh tomatoes in place of tomato paste.

The typical substitution for one can of 14.5-ounce of diced tomatoes is two cups of fresh chopped tomatoes while you obtain about 10 to 12 peeled tomatoes from a single 28-ounce tomato can or two 14.5-ounce cans.
