Since 1930, All American® Pressure Canner/Cookers have offered the best and safest method for home canning. The USDA recommends pressure canning as the only safe way to can meat, fish, poultry and vegetables. Pressure canner/cookers are available in a full range of sizes - big enough for preparing large quantities of food and pressure cooking inexpensive meat cuts to juicy tenderness quickly and easily. Only All American® Pressure Canner/Cookers feature an exclusive, precision machined "metal-to-metal" sealing system. Positive action clamping locks align the cover to the base, forming a steam-tight seal. Since the seal does not use a gasket, the cover can be easily opened and closed, providing an extra margin of safety over conventional rubber or composition gasketed cookers. All models feature a readable pressure gauge for accurate pressure control. They also include an easy to read instruction and recipe book.
