SPANISH HAM PRESERVING
The best way to preserve ham with bone is to keep it in a dry place with enough ventilation and a stable temperature (never in the fridge), far away from extreme cold and hot temperatures and preferably hanged or in a Parmesan ham holder. When you cut ham this part is exposed to environmental action , this creates a oxidation that makes dark this surface, fat becomes yellowish and this can cause nasty smells. So it is necessary to protect the cut of the ham placing a slice of fat or bark (of previous cuts) in order to keep superficial fat fresh and not resected, or covering the ham with a kitchen cloth.
At the moment of preserving the ham it is necessary to cover the cut with pieces of fat or bark, or with kitchen cloth
It is recommended to cut the quantity of ham that we think we are going to consume, in the opposite case there will be necessary to wrap it in transparent paper to avoid the contact with air.
