Preheat oven to 180C. Rub the interior of an ovenproof baking dish
with the cut side of the garlic clove, then generously with butter.

Scald the milk with the onion slices. Extract the onion and add the
slightly beaten egg, stirring until well incorporated.

Season with salt, pepper, and a dash of nutmeg.

Peel the potatoes and slice them thinly into the vegetable dish.

Pour the milk and egg mixture over the potatoes. Cover with the grated
cheese and dot with the remaining butter.

Bake 45 minutes. Serves 4.
