30REGULAR BAKING(continued)Oven ShelvesArrange the ovenshelf or shelves inthe desired locationswhile the oven iscool. The correctshelf positiondepends on the kindof food and thebrowning desired.As a general rule,place most foods in the middle of the oven, on eithershelf position B or C. See the chart for suggested shelfpositions. B will be used more than C.Type of Food Shelf PositionAngel food cake ABiscuits or muffins B or CCookies or cupcakes B or CBrownies B or CLayer cakes B or CBundt or pound cakes A or BPies or pie shells B or CFrozen pies A (on cookie sheet)Casseroles B or CRoasting A or BDCBAPreheatingPreheat 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, preheat10 minutes. After the oven is preheated, place thefood in the oven as quickly as possible to preventheat from escaping.Baking Pans Pan PlacementUse the proper baking pan. The type of finish on thepan determines the amount of browning that will occur.• Dark, rough or dull pans absorb heat resulting in abrowner, crisper crust. Use this type for pies.• Shiny, bright and smooth pans reflect heat, resultingin a lighter, more delicate browning. Cakes andcookies require this type of pan.• Glass baking dishes also absorb heat. When bakingin glass baking dishes, the temperature may need tobe reduced by 25°F.For 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 as wellas from the back of the oven, the door and the sides.If you need to use two shelves, stagger the pans soone is not directly above the other.
