they need to be washed, soaked, possible boiled or simmered, glazed, "roasted", sliced very thinly because it is strong, and oh so good. but it is not your ordinary supermarket water added product.
taditionally they are eaten in thin slices on biscuits, can be used in salads, soups, and other garnishes. It is not the kind of ham you take a huge slice from and sit down to eat with a side of mac and cheese. Altho thin chips of it might zip up a mac and cheese or cheese potato caserole.
