Steps in Canning Tomatoes
Ingredients
Directions
Prepare glass jars, rubbers, and tops. Heat jars to prevent breakage.
Pack whole tomatoes into jars, pressing them down without crushing.
Do not add liquid; tomatoes contain enough water.
For seasoning, add 1 teaspoon of salt or ½ teaspoon of sugar per quart if selling.
For home use, pack tomatoes tightly or crush broken ones to fill spaces.
Cut tomatoes for stews or soups to fit more in the jar.
Fit the rubber seal and ensure it lies flat against the jar.
Place the cover on the jar, tightening it until it catches, then loosen slightly.
