I have an old Hardwick gas oven. i can't seem to bake anything evenly despite having had the temperature tested by the gas company and told that it was accurate. i have tried using a cookie sheet under my baking pan and reducing the heat, however i still get an overly cooked outside and undercooked inside. there's no way in hell my landlord is going to replace the oven unless there's a safety issue or the thing is flat out broken.
any tips for baking with an old gas oven to get evenly cooked food?
