I have 8, 10 and and 12 inch stainless steel All-Clad skillets that are less than one year old. I can swear the 10 and 12 inch have warped. Only slightly but when I put the pan on the stove, with the weight of the handle, it is definitely not flat and there is a gap between the pan and the stove.
I bought All-Clad because I wanted something that lasts. I must say I am not very careful and I do deglaze with liquid when the pan is hot (no way around it, isn't it?).
Now I wonder if heat distribution will be as good.
Anybody out there with similar experience?
