Have six medium-sized potatoes baked. With a spoon carefully remove the potato, leaving the rest of the skin unbroken. Season the potato with one tablespoonful of butter, one tablespoonful of cream; salt, pepper to taste, stirring lightly with a fork; do not mash the potato. Add one cupful of any kind of chopped beef that has been moistened with gravy, stock and Worcestershire sauce. Fill the skins with this mixture, letting it rise a little above the top. Put a piece of butter on each and heat in the oven. Grated cheese may be used instead of meat.
