Canning is the process of hermetically sealing cooked food for future use. It is a preservation method, in which prepared food is put in glass jars or metal cans that are hermetically sealed to keep out air and then heated to a specific temperature for a specified time to destroy disease-causing microorganisms and prevent spoilage. Goodman's carries a full line of canning products and supplies including mason jars, canners, canning kits, lids, lables, pectin, canning salt, salsa mixes and more.
