Directions:
Wash some raw potatoes, peel them, cut them into very thin round slices.
Take a dish which will stand the oven, and be nice enough to go on the table, and put in it a layer of the slices sprinkled with pepper, salt, a little flour, and plenty of grated Gruyère. Continue in this way, finishing with a layer of cheese, and a little flour. Put the dish in the oven, which must not be a very hot one, and cook gently.

For a medium pie dish you will find that half an hour will be sufficient to cook the potatoes.
