T fal Pressure Canner, Pressure Cooker with 2 Racks and 3 PSI Settings, 22 Quart, Silver, Model 931052. With its roomy 22 quart capacity, this T fal polished aluminum pressure cooker and canner offers exceptional convenience in the kitchen. By combining heat, steam, and pressure, it efficiently cooks a wide range of healthy, delicious, home cooked meals in a fraction of the time up to 70 percent faster than conventional cooking methods, without losing essential nutrients or flavor. Cook for a crowd, create large batches for make ahead meals, or capture summer's bounty for enjoyment year round by canning fruits and vegetables. When canning, the cookware can hold 16 pint size jars, 26 half pint size jars (when double stacked) or 7 quart size jars at a time. The stovetop cookware's heavy gauge aluminum construction heats quickly and offers rustproof performance for long lasting use. Choose from three cooking pressure options 5, 10, or 15 PSI. The cooker's selective pressure control maintains a steady internal pressure, while its vent tube in the center of the lid allows for proper steam release. For added safety, the cookware's backup steam release components include a reusable overpressure plug (the red pin in center pushes out, releasing steam), and if more release is needed, the cookware's gasket release window will push out from the lid opening. In addition, a spring safety device prevents the pressurization of the cooker before being securely closed, and a sure locking lid system prevents opening the lid when the cooker is pressurized. A cooking rack comes included to prevent food from sticking to bottom and to raise jars up off bottom, along with a user guide with recipes for getting started. The T fal 22 quart polished aluminum pressure cooker and canner makes a great choice for novice and experienced cooks and canners alike.
