Hi all, so I just moved into a new house and went to bake my first batch of cookies. I use an oven thermometer so I checked and even though my temp was set at 375, therm. read 400 which is what I want - put cookies in and 12 minutes in, the cookies weren't done (normally they take 8.5) and at 13 mins, they were burnt! I watched the oven for the next 20 mins without cookies and the temp set at 375 ranged from 350-450 randomly. Any suggestions?! I have cookies due Monday!! Thanks in advance!
Intenta, colocando en 320 o 300 grados la temperatura y le pones tu termometro para ver que temperatura es la real. Es preferible hornear a temperatura mas baja, se demora mas pero no se te van a quemar. Poco a poco vas conociendo tu nuevo horno y ya cuando lo conozcas sabes que temperatura le debes colocar. Espero esto te ayude en algo
Most ovens do vary internally about 25F or so, but 100F is extreme. Call an appliance repair person. A controller or something is probably broken.
Oh, I missed the "cookies due Monday" part. If you can't get it fixed soon, then do as Patricia said - drop the temp and bake slower and longer. And rotate the sheets a lot especially if there is a hot spot.
Try a couple of thermometers in the oven too. Thermometers can also go bad, so perhaps it was just a measurement fluke and an isolated baking mishap.
Even so, you could probably get a repair person there in 24 hours.
