Pressure cookers raise water's boiling point

Sealed steam pushes the boiling point up, so food cooks far faster A pressure cooker traps steam, raising the internal pressure to roughly two atmospheres and pushing water's boiling point to about 120 degrees Celsius. Reactions that would take hours at 100 degrees, such as softening collagen in tough cuts, happen in a fraction of the time. The same principle explains why cooking times differ at high altitude, where the boiling point falls. It sits in Mondo's food collection, one of 200 facts that each trace back to the reference below.
