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 and Table
2.

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