It wasn't me after all

I've tried to bake a number of things: cookies, shortcakes, etc. in our oven. French ovens have an automatic timer that shuts off the oven automatically, but even after converting from Fahrenheit to Centigrade or vice versa, things always needed more time or they burned-- lots and lots more time.

My lovely housemate, when told of this problem, gave me an oven thermometer.

AHA!!!!

I set the temperature at 220/448°. It never got beyond 175/347° That's C to F and explains the problem.

It wasn't me...

A new oven is on the list.
