When you end up with a surplus of fresh tomatoes, one of the best things to make is canned tomato sauce. This basic canned (or jarred) tomato sauce contains just tomatoes, salt, and lemon juice, which assures a proper acidic environment for canning. Feel free to add any additional flavors (such as herbs) laterwhen you are ready to use the sauce. Fleshier plum tomatoes, like Roma or globe-shaped Early Girl tomatoes, are great to use since they have less juice, requiring less time to cook down the sauce.

You will need four pint-sized jars with sealable lids for canning; the lids and jars need to be sterilized, which can be done by boiling in a large pot for 10 minutes. Let them dry before filling. Canned tomato sauce will remain good for up to a year, stored in a cool, dark place.

"This was a tasty tomato sauce made with few ingredients. It does take time, but it is fairly easy. Tomato preparation (boiling, peeling, and removing seeds) takes about 30 minutes. Because some tomatoes are less acidic than others, the bottled lemon juice is added and the water bath processing is 40 minutes for pint jars." —Diana Rattray

  5. Put the coarsely chopped tomatoes in a pot with the salt and bring just to a boil. Reduce the heat to maintain a steady but gentle simmer and cook, stirring now and again, until the mixture is reduced by about a third, about 45 minutes. If at any point the mixture starts sticking to the pot, lower the heat and stir more often.

  9. Transfer the hot tomato sauce to the hot jars (a wide-mouth canning funnel works well), leaving about 1/2 inch of space at the top.

  10. Screw on the lids, put the jars in a canning rack, and lower them into the boiling water in the canning kettle. Process (boil) for 40 minutes. There needs to be at least an inch of water covering the jars, so keep an eye on the water level, adding more boiling water if needed.

  11. Remove the jars and let them cool. Store them in a cool, dark place (a cupboard or pantry works great) until you're ready to use some tomato sauce.

Alternative Way to Peel and Seed Tomatoes

Instead of blanching and then peeling and seeding the tomatoes, you can remove the skin and seeds using a food mill. Roughly chop the whole tomatoes and run them through the food mill; the skin and seeds will remain on top while the tomato pulp accumulates below.

Recipe Variations

  • Replace the lemon juice with 1/4 teaspoon of citric acid per pint jar or 1/2 teaspoon per quart jar.
  • Smooth Tomato Sauce: Chop the tomatoes and bring them to a boil in a large pot. Cook for 5 minutes, then put them through a food mill; discard the seeds, core pieces, and skin. Pour the pulp and juice back into the pot and bring to a boil; reduce the heat to low and simmer for about 40 minutes, or until the desired thickness is reached. Fill the sterilized jars and process as instructed.
  • Pressure Canner Processing: In a dial gauge pressure canner, process at 11 pounds pressure. In a weighted gauge pressure canner, process at 10 pounds pressure. Pints or quarts: 15 minutes.

Why Add the Lemon Juice?

Safe canning requires that the food has a guaranteed level of acidity, as the acid is what preserves the food and wards off bacteria (such as the type that causes botulism). Some of today's tomato varieties have low levels of acid, requiring an additional ingredient. In this recipe, the addition of bottled lemon juice lowers the pH level, creating the proper acidic environment for canning. Acidic ingredients, or foods with an added acid, are safe to can using a water bath, while all other foods need to be pressure canned.

Use 1 tablespoon of bottled lemon juice per pint jar, or 2 tablespoons per quart jar.
