Answer this question with another one: Do I master the slicing technique? If you have never sliced Spanish ham before or you feel insecure, the best thing to do is to order it already sliced because not only will you not hurt yourself, but you will get more Jamón than if you slice it yourself because our experts make the most of it.
On the other hand, the great advantage of ordering it sliced is that you can consume it as you need it over several months, while if you buy it whole (with bone) it is recommended to consume it in about three weeks and the ham shoulder in two weeks.
