I'd lived here less than a week when I figured out the oven bakes hotter than the degree stated on the dial, and hotter at the front than at the back.
I got used to it pretty quickly, dialing for 140 degrees instead of 180, for instance, most things turn out just fine.
Especially if I remember to rotate the pan throughout baking.
But things like custards?
Well, see for yourself:-
Egg custards before baking......
Egg custards after baking....
The others? Meh.
They were still yummy though.
