I bought a Lidl serrano ham chunk, it was fine in the fridge for weeks.
They keep these things on bars in Spain, unrefrigerated, and will take longer than 2 days to use, even in a busy bar, so the 'eat within 2 days' advice is bollocks, it's cured FFS.
I used it in a Spanish omelette. Ate quite a lot of it as part of a tapas plate with olives, bread, cheese, pickles.
When we were last in Spain, we discovered the 'serranito' which is a sandwich with a fried slice of serrano ham, thin pork loin slice, grilled green pepper and garlic mayonnaise, in a ciabatta style roll, which we really enjoyed, so we had a few of those.
You could make it into croquettes or fry slices of it with eggs.
I think it took us a couple of months to get through ours and it was absolutely fine. When I rule the world, I will ban 'throw away after 2 days' type instructions because they are completely unnecessary and lead to so much food waste.
