Because the effective cooking temperature is higher in the pressure cookeras high as 120 Â°C / 250 Â°Fthe cooking time can drop substantially. Take a look below at our cutaway photo from Modernist Cuisine at Home. The letters correspond to an explanation of each part of the pressure cooker. 1  High-pressure steam rapidly transfers heat to the surface of any food not submerged in liquid.
