Pressure canning is the only method guaranteed to safely can low-acid foods (meat, fish, vegetables), but this canner can also be used for high-acid foods like jams, jellies, and tomatoes. The Mirro® Pressure Canner is constructed from long-lasting aluminum and features an overpressure gasket window, an overpressure plug, and locking handles. This sleek kitchen companion will change the way you can!
