Preheating the Oven
It is important to preheat your oven before baking and roasting. Baked items depend on the correct oven temperature to help them rise and cook properly.
All Taste of Home recipes are tested in preheated ovens. This takes about 15 to 20 minutes and can be done while preparing the recipe. Place the oven racks at the proper levels first, then set to the recommended temperature.
