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.
Adjust lids and process following the recommendations in Table 1 and Table
2.
