How to Can Pumpkin and Winter Squash — Cubed

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 string-less, 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.

For why we say not to mash or puree the squash, read more about the caution.

Adjust lids and process following the recommendations in the Image Gallery.

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

Thank you so much! Was planning on canning some of our pumpkins soon. Wondering now if I purée it if it would freeze well.
