how to test your oven temperature
If you havenât done this before, I recommend that you do a few simple tests before you bake much more. Place the oven thermometer in your oven and and heat your oven to 350 degrees. I would heat it for one hour. After an hour, check the thermometer and see what the temperature is. You may want to tap the front of the dial to make sure the hands arenât sticking.
