Taking Your Oven’s Temperature
Ovens can lie. Yours may say 350° F, but your last batch of brownies was squishy even though you followed the baking time. What gives? After a while, ovens may lose accuracy, running up to 25 degrees too hot or cool. To test yours, place an oven-safe thermometer on the middle rack and heat the oven to 300° F; when the oven indicates it has reached that temperature, check the thermometer. If it reads 275° F, you’ll know that you need to set the temperature 25 degrees higher. Or seek a permanent fix by calling a repairman recommended by the manufacturer.
