Question about pressure cooker "jiggler weights"

[QUOTE="sophiecentaur, post: 6428450, member: 199289"] That's always a possibility but I suggest that you have not measured the relevant area where the pressure actually applies. There are so many cookers like that and they do work. Perhaps that just needs to be made clearer. Absolute pressure is what governs the boiling point of the water. A mechanism for controlling the pressure in the chamber may or may not be affected by external air pressure but a simple weight will be affected. The maximum pressure that you can expect inside a domestic pressure cooker won't be much more than 2Bar and that gives a cooking temperature of about 120C. Expected variations in ambient pressure are only about 5% so you could expect that sort of error in cooking temperature. Thankfully (for cooks), that's not much. [/QUOTE]
