I was given an enameled cast iron grilling pan. As I'm entirely inexperienced with cooking using either enameled cast iron or grilling pans, this is way out of my league. I am failing to use it for something as simple as grilling a sausage. I've tried a few times so far, and each time the result is the same: The sausage skin sticks to the pan, rips away from the sausage when trying to turn it, and the entire pan gets filled with a big black/brown burnt mess that requires loads of soaking and cleaning afterwards, no matter if I use some oil or none at all. My best attempt still looks like this
The instructions that came with the pan were pretty clear: Before first use, rinse with warm water and let air-dry. Then wipe some oil over the surface of the pan. Because I'm cooking on an induction plate, I'm supposed to pre-heat the pan for 5 minutes on a third of it's full power (to avoid thermal shock), then I can turn the heat all the way up. Dropping in a small drop of water it starts sizzling and evaporating immediately, which according to the internet is a sign the pan has reached the right temperature. I could try using more oil, but the whole purpose of a grilling pan (the reason I asked for one) was that you don't need to use any extra oil or butter to grill at all.
What else can I try to be able to use this pan properly?
