Yes, everybody makes basic cooking mistakes. Like, say, something as simple as overcooking mushrooms or toasting grains and spices. Below, reader Kerry Marie Evans confesses to burning pre-baked pizza to a crisp to associate food editor Rick Martinez. Here’s Martinez’s advice for making sure it never happens again.

Thanks,
Kerry

Taking Some Heat
The primary heat source in most consumer ovens is located at the bottom, and it’s either an electric coil or a gas burner. The heat radiates out from the element via thermal radiation and heats the walls of the oven and the surrounding air. The hot air rises and circulates throughout the oven and the heat radiates from the heated walls toward the center.

When you put a baking sheet or pan in the oven, you are breaking the circulation flow of the hot air and radiant heat from its element, deflecting and forcing it up and around the sides of the pan. Like the walls of the oven, the pan is bombarded with heat radiating from the element, which heats it up, like a pan on a …read more
