Canning Tomato Sauce

Quantity:
For thin sauce -- An average of 35 pounds is needed per canner load of 7 quarts; an average of 21 pounds is needed per canner load of 9 pints. A bushel weighs 53 pounds and yields 10 to 12 quarts of sauce-an average of 5 pounds per quart.
For thick sauce -- An average of 46 pounds is needed per canner load of 7 quarts; an average of 28 pounds is needed per canner load of 9 pints. A bushel weighs 53 pounds and yields 7 to 9 quarts of sauce-an average of 6-1/2 pounds per quart.

Procedure: Prepare and press as for making tomato juice. Simmer in large-diameter saucepan until sauce reaches 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 (See acidification directions). Add 1 teaspoon of salt per quart to the jars, if desired. Fill jars, leaving 1/4-inch headspace. Adjust lids and process. Recommended process times are given in Table 1, Table 2, and Table 3.
