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

QUALITY: 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
hot jars with cubes and cooking liquid, leaving 1-inch
headspace. Adjust lids and process.
For making pies, drain jars and strain or sieve cubes.
