   5      cups          hot diced cooked potatoes -- (about 6
                        -- medium-sized
                        -- potatoes)
   1                    egg yolk
   4      tablespoons   milk
     1/4  cup           butter
   1 1/4  teaspoons     salt
     1/8  teaspoon      pepper

Preparation:

Heat oven to 400 F. Partially mash potatoes with a potato masher. Add egg yolk, milk, butter, salt, and pepper. Beat with an electric mixer until smooth. If mixture is too stiff to drop from a spoon, add a tablespoon more milk. Drop spoonfuls on a lightly greased cookie sheet. Bake 12 to 15 minutes, until golden brown. This mixture may be piped with a pastry tube around a broiled steak on a heatproof platter or plank and broiled until golden brown.
