The bakery lady in Fresno told me my oven was running 25 degrees hot and I never checked it once
Stopped by a little bakery counter in Fresno on Saturday and got talking to the woman working there about why my cookies keep coming out with black bottoms. She said most home ovens are off by 25 to 50 degrees and that a $6 hanging thermometer changed her whole game years ago. I went home, hung one in the middle rack, and sure enough mine was running 25 degrees hot the whole time. Anybody else find out their oven was lying to them the hard way?
