Modern canning units take the guesswork out of canning at the right temperature and pressure to avoid mistakes.
First, keep your canning recipe and safety instructions handy.Wash tomatoes.
Half each tomato and place on a baking sheet.Space tomatoes so moisture can escape.8 minutes at 450°F.
After a few minutes, the tomato skins will pop off.Tomatoes should be peeled and deseeded.Put tomato halves in a pot (for sauce) or bowl for direct canning.
If making salso, dice tomatoes or continue as needed.I can whole tomatoes. Depending on my plans, I add garlic or basil to the tomatoes.
Some can sauces or soups before canning for quick meal prep. It depends on your cooking style.
