I received a cast-aluminum pan as a hand-me-down from my mother's grandmother. As far as I know it was never seasoned while in my mother's possession. A little food will stick on occasion and I wash it just as a I would a cheaper teflon-coated pan.
Can I / should I season the pan or am I better off just leaving it as it is? Anything else I should know about taking care of this guy? I'd like for it to last as long as possible.
