Why Some Tomato Varieties Are Better for Canning

You also want a tomato with a high flesh-to-skin ratio. That’s why cherry tomatoes aren’t used for canning.

FAQs

How do you peel tomatoes for canning?

Blanching is a quick and easy way to peel tomatoes before making sauce or canning. Cut a small x in the bottom of the tomato. Then, place tomatoes in boiling water for just a few seconds. 30 to 60 seconds should be enough, depending on the tomato size. Carefully lift the tomatoes with a slotted spoon and place them in a bowl of ice water. This will stop the cooking process and cool the tomatoes. Once they are cool enough to handle, the skin should peel right off at the x.

What tomatoes should not be canned?

Overly ripe tomatoes and those that have any spoilage should not be canned. These can increase the risk of spoilage in your final product and result in unsafe food.
