For the Zigouille Moustique, first remove the bread crust, dice the inside and place in a salad bowl. Pour hot milk over it. Once the bread is well soaked (after about 15 minutes), add the melted butter and grated alpine cheese.
Season with a little salt, a good pinch of nutmeg and freshly ground pepper. Complete with the eggs and a little crème fraîche. Mix everything together well and pour the mixture into a well-buttered gratin dish. Sprinkle with grated cheese and place in the oven at 200 °C for thirty minutes.
The zigouille moustique must be baked until evenly golden on the surface.
