The instructions that came with my new glass top cooking surface advised against using cast iron cookware. I love cooking with cast iron so I thought the enameled skillet would be my perfect solution.   The first time I used it my food stuck terribly.  Probably use error....perhaps I didn't use enough oil, perhaps my heat was too high.  With some serious scrubbing, I did get it cleaned and I oiled it and put it in the oven to "cure" as I have always done with cast iron.  All seems to be well now and I anticipate many happy years of use.
