Presto® 23-Quart Pressure Canner Pressure canning is the only method recommended safe by the U.S.D.A. for low-acid foods such as vegetables, meats and fish. The easy-to-read gauge automatically registers a complete range of processing pressures. Air vent/cover lock allows pressure to build up only when the cover is closed properly and prevents the cover from opening until pressure is safely reduced. This Presto® Pressure Canner also doubles as water bath canners for preserving fruits, jams, jellies, pickles and salsas. Constructed of extra-strong, warp-resistant aluminum and suitable for use on regular and smooth-top ranges. Includes cooking/canning rack and complete instruction and recipe book.
