India's Whistling Pressure Cookers - 0 views
-
The first whistle takes the longest, about 7 minutes, and indicates the cooker is fully pressurized, after which the heat is reduced, and the time is counted beginning with the next whistle. These cookers operate with oscillating pressures, cycling through building pressure and then releasing it with a whistling sound of escaping steam. Cooks in India rely on the whistle noise as a handy built-in timer.
