You can cook everything in a convection oven that you would normally cook in a conventional oven. Convection ovens maintain even, fast cooking because a fan circulates the hot air for even heat distribution. The temperature stays more consistent than a conventional oven which may have pockets of cooler air. Food cooks more evenly, in less time, and at lower temperature. Even heat distribution also ensures that the bottom of your food does not get burnt while the top is left raw. Convection ovens vary from countertop, to single stack to double stacked units. They are offered in gas or electric, and may feature steam injection, changes in fan speed and computerized controls.
