i picked up a super cheap comal at a little mexican store in central washington. forgot to ask what kind of metal it was made out of. too heavy to be aluminum. coated in something black (inside and outside). any ideas? i'm guessing steel, but the black coating throws me. don't figure it's a non-stick coating, as it's on the bottom of the pan as well.
also, tips on care and whatnot? everything i can find is talking about cast iron and clay comals.
