I am having several issues with my new De Buyer CS Mineral B Crepe pan. The most urgent one is that the two times I've used it, it sets the smoke alarm off. I use it on medium or under medium heat on my electric ceramic cooktop, and I use canola oil. I have cooked South Indian dosas on it, nothing else so far. Not sure what I'm doing wrong, or do most of you who use these pans put your vent fan on while you are cooking? Thanks all!
