All American 921 Pressure Canner vs All American 910 Pressure Cooker/Canner

Both are All American cast-aluminum canners with the metal-to-metal seal, so neither needs a rubber gasket to wear out. The 921 is the larger unit, holding about 17 quarts of jars, and suits households that can in big batches; the 910 is the smaller, lighter 10.5-quart model that is easier to lift and store. Owners praise the gasket-free seal and long life on both, and the main trade-off is batch size against weight and footprint.

• Choose the All American 921 if you can in large batches, want to process more jars per load, and can handle a heavy 29-pound canner on a gas or electric coil burner.
• Choose the All American 910 if you can in smaller batches, want a lighter canner that is easier to lift and store, and have limited burner space.
