1. Preheat the oven to 350 degrees F. 2. Lightly butter a 10-cup gratin dish. 3. Rub the dish with both halves of the cut garlic clove. 4. Combine the cream, nutmeg, salt, pepper, and cayenne in a bowl. 5. Peel the potatoes and slice them paper-thin on a mandoline. 6. As you work, place the potato slices in the bowl with the cream and seasonings. 7. Add the gruyere and combine thoroughly. 8. Pour the potato-cheese mixture into the prepared gratin dish, making sure the potato slices are flat and level. 9. Place the gratin dish inside a roasting pan and fill the pan to three quarters full with hot water, creating a bain-marie. 10. Carefully place the bain-marie in the center of the oven and bake for 2 hours, or until completely set and golden on top. ---------------------------------------------------------------------------
