Preparing and Canning: Clams1
United States Department of Agriculture, Extension Service2Procedure: Keep clams live on ice until ready to can. Scrub shells thoroughly and rinse, steam 5 minutes, and open. Remove clam meat. Collect and save clam juice. Wash clam meat in water containing 1 teaspoon of salt per quart. Rinse and cover clam meat with boiling water containing 2 tablespoons of lemon juice or 1/2 teaspoon of citric acid per gallon. Boil 2 minutes and drain. To make minced clams, grind clams with a meat grinder or food processor. Fill jars loosely with pieces and add hot clam juice and boiling water if needed, leaving 1-inch headspace.
Adjust lids and process following the recommendations in Table 1 or Table 2 according to the canning method used.
