¡good news!
you do not ever have to worry about your jamon serrano spoiling. generally serrano ham can be as old a few years already by the time you get it... it is cured by a saline method, and so there is no mold (or very few) that can grow on it... (similar to any cured food products, like salmon, cod, et cetera...).
but i agree that it's best to cover up with a cloth on the jamonera... it can get dusty if you have a single leg of it for over a year...
the best: pan normal (crispy outside, soft inside), lonchas de jamon, tomate verde, aceite de oliva, sal, y un vaso de tinto... ¡¡un bocadillo de la *$#@ madre!! (i shouldn't talk like that!
)
pd> yeah, prosciutto is good, but not as good... and it's true, you do have to slice off mold if you have the jamon in a humid place...
