For best air circulation
Hot air must circulate around the pans in the oven for even heat to reach all parts of the oven. This results in better baking.
l Place the pans so that one is not directly over the other.
l For best results, allow 1l/z to 2 inches
l Use only one cookie sheet in the oven at one time.
Use the following as a guide to determine where to place the pans:
One pan
Place in the center of the oven rack.
Two pans
Place in opposite corners of the oven rack.
Three or four pans
Place in opposite corners on each oven rack. Stagger pans so no pan is directly over another.
Using aluminum foil for baking
Use aluminum foil to catch spillovers from pies or casseroles:
l Place the foil on the oven rack below the rack with the food. Turn up foil edges and make sure foil is about 1 inch (3 cm) larger all around than the dish holding the food.
l Do not cover the entire rack with aluminum foil. It will reduce air circulation and cause poor cooking results.
l Do not line oven bottom or entire oven rack with foil or other liners. Poor baking will result.
