Preheating
Preheat the oven if the recipe calls for it. To
preheat, set the oven at the correct temperature.
and pan
Preheating is necessary for good results when
placement
baking cakes, cookies, pastry and breads.
For ovens without a preheat indicator light or tone,
preheat 10 minutes.
Aluminum
You can use aluminum foil to line the broiler
pan and broiler grid. However, you must mold
foil
the foil tightly to the grid and cut slits in it just
like the grid.
Aluminum foil may also be used to catch a spillover.
Never entirely cover a rack with aluminum foil.
This will disturb the heat circulation and result
in poor baking.
A smaller sheet of foil may be used to catch a
spillover by placing it on a lower rack several
inches below the food.
Baking results will be better if baking pans are
centered in the oven as much as possible. Pans
should not touch each other or the walls of the
oven. If you need to use two racks, stagger the
pans so one is not directly above the other, and
" between pans, from
leave approximately 1 1 ⁄
2
the front, back and sides of the wall.
Cut slits in the foil just like the grid.
