Need help with baking sheet problem
I'm having trouble finding the right baking sheet for cookies. I have been using a Chicago Metallic 12 x 18 nonstick sheet pan, and I am finding that it drastically raises the oven temp (seen in the hanging thermometer) to an unpredictable level in my very small oven.
I tried a new recipe for peanut butter cookies last night, and I preheated the oven to 325, which was 25 degrees lower than what the recipe called for. About 5 minutes later I checked the hanging thermometer in the oven, and the temperature had shot up to 400, burning the bottom of the cookies before they were fully baked.
I'm not able to buy a new oven as of yet, so I'd like to see if I can find an inexpensive solution to this problem. It seems impossible to figure out what temperatures to preheat the oven to. Thanks in advance for any suggestions!
