Though we still catch ourselves thinking of tomatoes as a vegetable, they're actually a fruit—and they behave like one when they're canned. Because tomatoes have a high acidity, they can be canned just like other fruits with only a splash of added citrus or vinegar. You can process tomatoes whole, crushed, or halved. Home-canned tomatoes will bring a garden-fresh taste to soups, stews, chilis, and spaghetti sauce all year long. For each pint of canned tomatoes, you will need 1-1/4 to 1-1/2 pounds ripe tomatoes; for each quart, you'll need 2-1/2 to 3-1/2 pounds ripe tomatoes. Choose unblemished tomatoes for canning and wash well in cold water. Once your tomatoes are ready, follow our instructions below for peeling, canning, and freezing fresh tomatoes.
