A method of preserving food by hermetically sealing it in glass containers. The use of special canning jars and lids is essential for successful canning. The canning process involves quickly heating jars of food to high temperatures, thereby retaining maximum color, flavor and nutrients while destroying the microorganisms that cause spoilage. During processing, the food reaches temperatures of 212°F (with the boiling-water-bath method) to 240°F (using a pressure canner). Any air in the container is forced out between the jar and lid. A vacuum is created as the food cools and contracts, sucking the lid tightly to the jar. This airtight seal is vital to prevent invasion by microorganisms. Refer to a general cookbook for specific instructions on canning foods.
