14BAKING(continued)PreheatingPreheat the oven if the recipe calls for it. Preheatmeans bringing the oven up to the specifiedtemperature before putting the food in the oven.To preheat, set the oven at the correct temperature—selecting a higher temperature does not shortenpreheat time.Preheating is necessary for good results when bakingcakes, cookies, pastry and breads. For most casserolesand roasts, preheating is not necessary. For ovenswithout a preheat indicator light or tone, preheat 10minutes. After the oven is preheated place the foodin the oven as quickly as possible to prevent heatfrom escaping.Pan PlacementFor even cooking and proper browning, there must beenough room for air circulation in the oven. Bakingresults will be better if baking pans are centered asmuch as possible rather than being placed to the frontor to the back of the oven.Pans should not touch each other or the walls of theoven. Allow 1– to 11⁄ 2–inch space between pans aswell as from the back of the oven, the door and thesides. If you need to use two shelves, stagger the pansso one is not directly above the other.Cookies Aluminum FoilWhen bakingcookies, flat cookiesheets (without sides)produce better-looking cookies.Cookies baked in ajelly roll pan (shortsides all around)may have darkeredges and pale orlight browningmay occur.Cookies can be baked on several shelves at thesame time but browning may be uneven becauseof reduced air circulation.Do not use a cookie sheet so large that ittouches the walls or the door of the oven.Never entirelycover a shelf withaluminum foil.This will disturb theheat circulation andresult in poorbaking.A smaller sheet offoil may be used tocatch a spillover byplacing it on a lowershelf several inches below the food.Do not put aluminum foil on the oven bottom.Baking GuidesWhen using prepared baking mixes, follow package recipe orinstructions for best baking results.
