Mushrooms

Mushrooms - Whole or Sliced

Quantity: An average of 12.8 pounds is needed per cannier load of 8 pints; an average of  6.66 pounds is needed per canner load of 8 half-pints – an average of 2 pounds per pint.

Quality: Select only brightly colored, small to medium-size domestic mushrooms with short stems, tight veils (unopened caps), and no discoloration. Caution: Do not can wild mushrooms.

Procedure: Trim stems and discolored parts. Soak in cold water for 10 minutes to remove dirt. Wash in clean water. Leave small mushrooms whole; cut large ones. Cover with water in a saucepan and boil 5 minutes. Fill jars with hot mushrooms, leaving 1-inch headspace. Add 1/2 teaspoon of salt per pint to the jar, if desired. For better color, add 1/8 teaspoon of ascorbic acid powder, or a 500-milligram tablet of vitamin C. Add fresh hot water, leaving 1-inch headspace.
