Wash, peel, and trim tomatoes; leave whole or cut in half. Add 2 tablespoons bottled lemon juice or 1/2 teaspoon citric acid to quart jars. Use half this amount for pints. Add 1 teaspoon salt per quart (1/2 teaspoon per pint) to jars, if desired.

Storing whole tomatoes in a zip-top bag in the freezer is an unglamorous, but extremely effective (and easy!) way of preserving tomatoes for future seasons. It's not even necessary to peel them beforehand, as frozen tomatoes are even easier to peel than fresh.

First, pour some olive oil into the pot and heat it over medium heat. Then, add the canned tomatoes to the pot and let them cook for about 10 minutes. After 10 minutes, add some garlic, basil, salt, and pepper to the pot and let everything cook for another 20 minutes. And that's it!

As when using fresh tomatoes, add a can of diced tomatoes to the food processor to blend them a bit, taking the tomatoes from the diced to the crushed state. Just remember to leave the mixture chunky and not turn it into a sauce. Add some tomato paste to these as well to improve upon the flavor and consistency.

Do not can damaged tomatoes or those from dead or frost-killed vines. These tomatoes may have harmful pathogens. The canning process time may not be enough to kill disease organisms. This could lead to a product that spoils and is unsafe to eat.

You can turn whole tomatoes into whatever you need, tearing or crushing them with your hand (or cutting them in the can with kitchen shears), pureeing with a blender or food processor or chopping with a knife. Don't want seeds? Run the tomatoes through a food mill.

First, the skins are removed, either by steaming or a hot bath. Next, the tomatoes go into cans along with salt and a filler, either tomato juice or puree. (Be aware added salt can bring up the sodium count in your recipe.) Finally, the can is sealed, heated and held at temperature until the contents are sterile.

If the tomatoes have not been acidified prior to canning you are risking the possibility of bacterial growth, which can be fatal. If you just canned them, and they haven't been stored, you might be able to open the jars and start over, or maybe freeze them.

Why put lemon juice in canned tomatoes? ›

Citric acid, bottled lemon juice, or vinegar added in the correct amounts will ensure that whether tomatoes are boiling water bath canned or pressure canned, the C. botulinum spores will not germinate when a current recipe is used and the jars are processed properly.

Add ½ teaspoon per quart or ¼ teaspoon per pint. Citric acid also is used to preserve the color of fresh cut fruit or as a pretreatment for frozen and dried fruit (see Color Enhancers and Colorants section).

If the canned whole tomatoes are stored in a cool, dry place, unopened and away from direct sunlight, they can last up to 2-5 years beyond the printed best-by date. It's important to check the can for any signs of damage, such as dents or bulges, as this can indicate spoilage.

As glass jars became more widely available, however, Italians began preserving their tomatoes by filling jars with their homegrown produce and submerging them in boiling water for sterilization. This process, known as “bain-marie,” is still used today.

Canning: Canning is a popular method for preserving tomatoes. To can tomatoes, you will need a pressure canner or a water bath canner. First, wash and sterilize canning jars and lids. Then, boil the tomatoes for a few minutes, remove the skin and stem, and pack them tightly into the jars.

Remove garlic and herbs, as they can spoil and are not safe for preserving, then add the tomatoes to a sterilized jar (thoroughly washed with soapy hot water). Cover completely with olive oil and store in the refrigerator for 4ish weeks, just make sure they stay completely submerged in the oil.
