Aluminum foil on bottom of oven
I keep aluminum foil on the bottom of my oven to keep it clean. Today my daughter was making cupcakes, the tops were perfect, the bottoms burned. She never had this happen before, and this was her first time in this oven. I know the temp is accurate, I checked it with a thermometer. Could the foil be reflecting heat or something? She's made lots of cupcakes, they are her specialty, just wondering if the foil might cause it. Thanks
