Presto® Pressure Cooker Regulator with a Slow, Gentle Rock
On a weighted gauge pressure cooker, when 15 pounds pressure is reached inside the pot, the pressure regulator begins to rock. On ALL kinds of pressure cookers, it is important to reduce the heat on the stovetop once pressure is reached. The regulator should be rocking gently and slowly as shown in this video. Just enough so you can hear that it is doing its job. If the heat isn’t reduced, too much liquid will be released while the cooker is trying to maintain 15 pounds pressure. If excess steam is allowed to escape, the cooker may boil dry, the food may scorch, and/or the cooker may be damaged.
