I really enjoyed reading all your thoughts on whats good and bad about cast iron pans, so I decided to highjack the post.(a compliment I assure you). I recently got my first carbon steel deBuyer pan and so far I love it. I was wondering what I couldn't make in this pan. I seem to recall hearing that its not great for tomato based sauces. but beyond that I'm in the dark. Any tips would be great.
