Mondo Knows Facts

Oven dials are often wrong by degrees

Domestic ovens swing around the set point rather than holding it steady A domestic oven usually cycles its element on and off, so the temperature rises and falls by 10 to 20 degrees around the setting. The dial is also calibrated loosely, and hot spots near the back or above the element can differ from the middle by far more. An oven thermometer left inside shows what is really happening. It sits in Mondo's food collection, one of 200 facts that each trace back to the reference below.
