Pressure canners are super versatile for preserving as they can be used under pressure to preserve non acidic foods like meat, poultry and vegetables or without pressure as a hot water bath for acidic foods.
Pressure canners can be used on most stove tops except induction stove tops. If you have a glass stove top you need to check the manufacturer's weight rating for the glass as a canner filled with jars of food can be very heavy.
Some preservers choose to have a separate stand alone gas burner for pressure canning: as these can be used outdoors it can save cluttering up the kitchen during preserving season!
Do not mistake a pressure cooker for a pressure canner: whilst a pressure canner can be a pressure cooker, the reverse does not apply!
Ozfarmer stocks the Presto brand and the All American brand of pressure canners.
