Ingredients: Potatoes, butter, Parmesan, white stock, cream, pepper, salt.

Boil two pounds of potatoes in salted water for a quarter of an hour, peel and cut them into slices about the size of a penny, then arrange them in layers in a very deep fireproof dish (with a lid), and on each layer pour a little melted butter, a little good white stock and a dust of grated Parmesan. Reduce a pint and a half of cream to half its quantity, add a little pepper, and pour it over the potatoes. Put the dish in the oven for twenty minutes. Serve as hot as possible.
