This is a classic French bistro dish which I fell in love with when I lived in the Alps for a season. Traditionally it uses Reblochon cheese, which is a Savoie speciality, and is definitely worth sourcing! The recipe and method itself is very simple, with few ingredients, yet it produces a filling dish which needs only a crisp green salad (and some wine!) as an accompaniment.
