DAE buy a $6 oven thermometer and find out their dial was off by 40 degrees?
Kept getting sunken cakes at my place in Boise and figured it was my mixing, so I grabbed a cheap oven thermometer at the hardware store on State Street. Turned out the dial says 350 but it really runs about 310, so every bake was underdone in the middle. Now I just set it 40 higher and my banana bread finally comes out clean on the toothpick test. How far off was your oven, and did you fix it or just bake around it?
