Pressure's Speed Trick
How does a pressure cooker cook food faster?
You drop potatoes into boiling water and wait. And wait. And wait some more. But put those same potatoes in a pressure cooker, seal the lid, and twenty minutes later — dinner's ready. What kind of sorcery is this?
The secret starts with a simple fact: water doesn't always boil at the same temperature. Up on a mountain, where the air is thin and pressure is low, water boils at only 85°C. Your pasta takes forever to cook up there because cooler water does less work.
