Pressure canning is the only method recommended safe by the U.S.D.A. for low-acid foods such as vegetables, meats and fish.
No matter how high you turn up the heat, boiling water cannot surpass 212°F (even lower at high altitudes). All-American's High-Quality Pressure Canners bring jar temperatures up to 250°F at just 15 lbs sq. in.
Note: Glass-top ranges are not designed for the high heat of canning.
