I'm considering getting a cast iron skillet. I just made the switch from teflon to stainless and am thinking about going for cast iron.
I'm sure many of you have seen the videos here, particularly the first one in the blog post.
Is the process for preheating cast iron similar? Would you get a similar mercury ball / "Leidenfrost effect"? Is that even what you want when preheating cast iron?
If it makes a difference, I think I would just go with a Lodge chef's skillet, with the rounded sides.
