Once the ham has been opened, how is it preserved and how long does it last in good condition?

Once opened, the cut surface should be covered with a clean, opaque cotton cloth to protect it from light. It can also be covered with plastic wrap, but not for long, as mold may develop since it does not breathe.

We recommend consuming a whole ham within 6 to 8 weeks of opening (3 to 4 weeks in the case of shoulder hams) to enjoy its freshness and original flavor notes without organoleptic loss due to excessive drying.
(Technical note: We advise against the popular myth of covering the cut with the ham's own yellow fat, as this fat quickly turns rancid in open air and imparts an unpleasant flavor to the fresh meat.)
