Place the potatoes and leaves in a pot, cover with water and put a lid on. Bring to a boil and cook until done, but do not over-cook.

Plate the potatoes on a hot stone and cover them completely with the leaves. Serve some good butter on the side and explain to your diners how to unearth them from the leaves with their hands, crush them in their fingers and dip them in butter in order to enjoy the experience to the full.
