I'm looking for a pan for my girlfriend, she hardly ever has time to cook and we don't live together, but both of us would like her to have something at her place that we can use to get a nice sear on meat, but is nonstick enough for fish fillets. Carbon steel would be my choice, but as it will only be used a few times a month at most, and we live in a high humidity climate, I'm a bit worried it will rust all the time and be annoying to maintain. Stainless/clad is not really an option because of the learning curve involved and the lack of time she has for that.
is there any other type of material i have forgotten about? This will mainly be used for searing meat, fish, potatoes, pancakes, crepes and the like. Ideally it shouldn't be too heavy. No nonstick coatings as she already has nonstick pans and we don't like how it browns.
