Potatoes, Sweet–Pieces or Whole
It is not recommended to dry pack sweet potatoes.
Quantity: An average of 17-1/2 pounds is needed per canner load of 7
quarts; an average of 11 pounds is needed per canner load of 9 pints.
A bushel weighs 50 pounds and yields 17 to 25 quarts–an average of 2-
1/2 pounds per quart.
Quality: Choose small to medium-sized potatoes. They should be mature
and not too fibrous. Can within 1 to
2 months after harvest.
Procedure: Wash potatoes and boil or steam until partially soft (15
to 20 minutes). Remove skins. Cut medium potatoes, if needed, so that
pieces are uniform in size. Caution: Do not mash or puree pieces.
Fill jars, leaving 1-inch headspace. Add 1 teaspoon salt per quart to
the jar, if desired. Cover with your choice of fresh boiling water or
syrup, leaving 1-inch headspace.
