Bring a pot of water to boil. Then add salt. Boil potatoes in salted water for 5 minutes. Remove from water and drain.
Take out a small casserole dish and rub the surface with butter.
Put 1/4 of the cream at bottom. Then lay down 1/3 of the potatoes. Season with black pepper and sprinkle 1/3 of the cheese. Repeat until all potatoes are used up. Top with cream and another layer of cheese.
Cover with foil and bake at 375 degrees F for 40 minutes.
Then broil at 400 degrees for 5 mins until the cheese is golden brown at the top.
