The smart choice for preparing today's lower calorie foods. Foods cook 3 to 10 times faster than ordinary cooking methods, saving time, energy, and money. Pressure cooking preserves flavors and nutrients, and even tenderizes lean cuts of meat. Strong, heavy-gauge aluminum for quick, even heating. Works on electric, smooth-top, and gas ranges. Pressure regulator maintains the proper cooking pressure automatically. Fully immersible and dishwasher safe with the sealing ring and over-pressure plug removed.
