Canned Tomatoes
2 1/2 pounds tomatoes per quart - (to 3 1/2 lbs)
Packaged citric acid or bottled lemon juice
Salt -- (optional)

Note: Because the acid in tomatoes varies, they take special handling to process in a hot-water bath. Never tinker with the amount of citric acid or lemon juice, and use bottled, not fresh lemon juice (fresh can vary in the amount of acid, so bottled is more reliable).

The amount of acid and the processing times vary according to how densely the tomatoes are packed, so choose a recipe that matches the type of pack you are using. In this version, cooked tomatoes are packed with water and citric acid or lemon juice.

Wash jars and bands in hot, soapy water. Cover lids with hot water according to package directions. Place jars on rack in deep pot of boiling water. Turn off heat and let jars stand at least 10 minutes or until ready to use. Wash tomatoes. Place in boiling water for 30 to 60 seconds, then put in ice water to loosen skins. Peel, core and remove any greenspots from tomatoes. Leave tomatoes whole or cut into halves or quarters.

Place tomatoes in a saucepan; add just enough water to cover. Boil tomatoes gently for 5 minutes. Add 1/2 teaspoon citric acid or 2 tablespoons bottled lemon juice per quart jar, or 1/4 teaspoon citric acid or 1 tablespoon bottled lemon juice per pint jar. Pack tomatoes into hot jars, leaving 1/2-inch headspace.

Ladle hot cooking liquid or boiling water over tomatoes, leaving 1/2-inch headspace. Add 1 tablespoon salt to each quart jar or 1/2
teaspoon salt to each pint jar, if desired. Remove air bubbles with a nonmetallic spatula.

Adjust two-piece caps. Place jars on rack in deep pot of water. Cover and bring water to a boil. Process pints for 40 minutes, quarts for 45 minutes.

Remove jars from hot water and place on dish towels. Let stand several hours or overnight. Check seals.
