Are all frying pans supposed to be flat on the inside?
I've done some research already, but haven't been able to find an answer to my question yet - hence my first post on this forum.
Do you know if some frying pans/skillets could have a non-flat interior on purpose?
By non-flat I mean higher in the middle and lower around the sides, so that oil accumulates around the side and the middle of the pan stays relatively dry.
I've noticed this on my thick-bottomed aluminium non-stick pan, and also on a friend's enameled cast iron sautoir/round roasting pan.
I know cheap thin pans used on electric stoves will warp in a similar way, but it seems the pans I used were made that way on purpose.
Does this sound possible? What could be the point in this?
All of my skillets and saucepans are flat on the bottom, except for the copper skillet and sauté pan, both of which are quite old. I've always assumed that was long-term warpage. The copper saucepans show no such deformation, but they run at a lower heat level anyway. I've got (I think) three nominal 8" iron skillets and a mess of smaller ones, down to a little salesman's sample I cook one egg on now and then just for fun. Got a steel frypan too. All flat-bottomed.
Frying pans should be flat so that you have an even layer of oil. Otherwise things in the center of the pan will singe.
