Canning Corn - Whole Kernel
Quantity: An average of 31-1/2 pounds (in huss) of sweet corn is needed per canner load of 7 quarts; an average of 20 pounds is needed per canner load of 9 pints. A
bushel weighs 35 pounds and yields 6 to 11 quarts--an average of 4-1/2 pounds per quart.
Quality: Select ears containing slightly immature kernels or of ideal quality for
eating fresh. Canning of some sweeter varieties or too immature kernels may cause
browning. Can a small
amount, check color and flavor before canning large quantities.
Procedure: Husk corn, remove silk, and wash. Blanch 3 minutes in boiling
water. Cut corn from cob at about three-fourths the depth of kernel.
Caution: Do not scrape cob.
Hot pack--To each clean quart of kernels in a saucepan, add 1 cup of hot water,
heat to boiling and simmer 5 minutes. Add 1 teaspoon of salt per quart to the jar, if
desired. Fill jars with
corn and cooking liquid, leaving 1-inch headspace.
Raw pack--Fill jars with raw kernels, leaving 1-inch headspace. Do not shake
or press down. Add 1 teaspoon of salt per quart to the jar, if desired.
Add fresh boiling water, leaving 1-inch headspace.
Adjust lids and process following the recommendations in Table 1 or Table 2 according the
the method of canning used.
