The single most convenient, time and energy saving piece of cookware in my kitchen is my pressure cooker. Most of my meals are ready in 15 minutes, which is at least a third of the time it would take to prepare them the usual way. Presto Pressure Cooker was my first pot I ever bought, and used it for over 20 years. During this time I only had to replace the gasket, and the pressure regulator (which I misplaced). Last year I finally let it retire, and replaced it with Splendid 2 in 1 Pressure Cooker by Fagor.
