This is the only method recommended safe by the U.S. Department of Agriculture for canning low-acid foods such as vegetables, meats, poultry and fish. The deluxe pressure dial gauge registers the complete range of processing pressures.

It doubles as a boiling-water canner for preserving fruits, jams, jellies, pickles and salsa. Special air vent/cover lock allows pressure to build only when the cover is closed properly and prevents the cover from being opened until pressure has safely dropped. It also gives a visual indication of pressure inside the canner. Constructed of warp-resistant heavy-gauge aluminum for fast, even heating. Includes canning rack and complete 76-page instruction and recipe book. Works on regular and smooth-top ranges. Extended 12 Year Limited Warranty. Regular Mason Jar Capacity: 24 Half-pints, 20 Pints and 7 Quarts. This Presto® canner/cooker has a 23-quart liquid capacity (21.8 liters).
