Canning Tomato Sauce

Ingredients (for thin sauce): a bushel of tomatoes weighs an average of 53 pounds and yields 10 to 12 quarts; an average of 5 pounds per quart

  • Per canner load of 7 quarts an average of 35 pounds is needed
  • Per canner load of 9 pints an average of 21 pounds is needed

Ingredients (for thick sauce): a bushel of tomatoes weighs an average of 53 pounds and yields 10 to 12 quarts; an average of 6-½ pounds per quart

  • Per canner load of 7 quarts an average of 46 pounds is needed
  • Per canner load of 9 pints an average of 28 pounds is needed

Quality of ingredients: select only disease-free, preferably vine-ripened, firm fruit

Directions: prepare and press as for making tomato juice. Simmer in a large-diameter saucepan until the sauce reaches the desired consistency. Boil until volume is reduced by about one-third for thin sauce, or by one-half for thick sauce. Add bottled lemon juice or citric acid to jars (acidification directions if needed). If desired, add 1 teaspoon of salt per quart to the jars. Fill hot jars, leaving ¼-inch headspace. Remove air bubbles and adjust headspace if needed. Wipe rims of jars with a dampened clean paper towel. Adjust lids and process.

Recommended Canner Type: Boiling-water canner (making sure acidity is correct)
