Oven Thermometer

Oven thermometer
An oven thermometer lets you know the actual oven temperature, which may not match the temperature on the dial.

Not only is there no bell that rings when the oven is sufficiently preheated, chances are the internal temperature won’t match what’s on the dial. Use an oven thermometer solve both problems. My oven takes at least 10 minutes to preheat, and it’s usually about 10 degrees hotter than the dial.
