To Figure Yield of Canned Fruit From Fresh

The number of quarts of canned food you can get from a given quantity of fresh fruit depends upon the quality, variety, maturity, and size of the fruit, whether it is whole, in halves, or in slices, and whether it is packed raw or hot.

Generally, the following amounts of fresh fruit or tomatoes (as purchased or picked) make 1 quart of canned food:

Pounds
Apples 2½ to 3
Berries, except strawberries 1½ to 3 (1 to 2 quart boxes)
Cherries (canned unpitted) 2 to 2½
Peaches 2 to 3
Pears 2 to 3
Plums 1½ to 2½
Tomatoes 2½ to 3½

In 1 pound there are about 4 medium apples, peaches, or tomatoes; 3 medium pears; 12 medium plums.
