Quick Answer
Yes, you can pressure can food in glass containers, but they must be specifically designed and rated for pressure canning.
Choosing the Right Container
When selecting a glass container for pressure canning, look for jars that are specifically designed and rated for this purpose. Brands like Mason, Kerr, and Bernardin offer pressure-safe glass jars with matching lids and rings. The jars should be labeled as “pressure canning safe” and meet the standards set by the USDA.
Preparing the Container
Before using a glass container for pressure canning, make sure to check the manufacturer’s instructions for any specific guidelines or recommendations. Typically, you’ll need to ensure the lid and ring are properly assembled, and the jar is clean and dry. Remove any labels and residue from the jar using a gentle cleanser and water. Sterilize the jar, lid, and ring by submerging them in boiling water for 10-15 minutes.
Pressure Canning Techniques
When using glass containers for pressure canning, it’s essential to follow the same general techniques as when using metal cans. This includes maintaining the recommended pressure, temperature, and processing time for the specific food being canned. A pressure canner should be set to 10-15 PSI (pounds per square inch) and maintained for the recommended processing time, usually 20-30 minutes. Always refer to a trusted resource, such as the USDA’s Complete Guide to Home Canning, for specific guidelines and recommendations for pressure canning with glass containers.
