Mondo Knows Facts

Fan ovens brown food more quickly

Moving air strips moisture and delivers heat faster than still air A convection oven uses a fan to circulate hot air, which keeps replacing the cool, moist layer that forms around food in a still oven. Without that insulating blanket, surface water evaporates sooner and browning begins earlier, so recipes usually call for a temperature about 20 degrees lower. The effect is strongest on thin items and on anything roasted uncovered. It sits in Mondo's food collection, one of 200 facts that each trace back to the reference below.
