what can i use instead of baking tray for making cookies?
Tin foil and tin cans were never made of tin
Tin is a metal that can deteriorate,rust and poison food.Aluminum doe'snt.
You really are going to need a baking tray or baking sheetYou can turn your baking pan that the stove came with upside down, cover with foil and use it that wayYou can also use a 9 x 13 baking dish in the same manner Foil placed directly on the racks won't hold the cookies properly and they are likely to burn on the bottoms before they cook through You can buy disposable foil pans for this purpose, by the way.
