Pressure Cooker Accessory: Canning

Accessories for pressure cookers specifically labeled as Pressure Cookers/Canners by the manufacturer. All pressure canners can be used as pressure cookers, not all pressure cookers can be used as pressure canners – according to the USDA for a cooker to be considered a canner it must be able to hold four quart-sized jars. Currently no electric pressure cookers can be used for pressure canning – even if they may have been advertised by the manufacturer as being able to do so the National Center for Home Food Preservation (an off-shoot of the USDA) specifically published an announcement saying they have not approved pressure canning in these devices.
