. . but if your cooking has a long simmering phase after frying, it's less than ideal. Enameled Iron is where it's at then.
I have a general 9" frying pan which is kept properly seasoned and a sheet steel (better temperature control and shape) omelet pan. The omelet pan never sees water, but the frying pan gets scrubbed out and reseasoned when it gets too much build-up on the sides.
Grape seed oil works very well for seasoning.
