Preparing Pumpkins and Winter Squash: Cubed for Canning1

United States Department of Agriculture, Extension Service2

Quantity: An average of 16 pounds is needed per canner load of 7 quarts; an average of 10 pounds is needed per canner load of 9 pints -- an average of 2-1/4 pounds per quart.

Quality: Pumpkins and squash should have a hard rind and stringless, mature pulp of ideal quality for cooking fresh. Small size pumpkins (sugar or pie varieties) make better products.

Procedure: Wash, remove seeds, cut into 1-inch-wide slices, and peel. Cut flesh into 1-inch cubes. Boil 2 minutes in water. Caution: Do not mash or puree. Fill jars with cubes and cooking liquid, leaving 1-inch headspace.

Adjust lids and process following the recommendations in Table 1 or Table 2 according to the method of canning used.

For making pies, drain jars and strain or sieve cubes.

*After the canner is completely depressurized, remove the weight from the vent port or open the petcock. Wait 10 minutes; then unfasten the lid and remove it carefully. Lift the lid with the underside away from you so that the steam coming out of the canner does not burn your face.
