For the dough, whisk together milk, eggs and salt.
Stir in flour until a smooth batter is formed.
In a frying pan with little fat, bake narrow pancakes until light brown.
Spread the pancakes thickly with fonduta, fold into rolls and place in a lightly buttered gratin dish. Sprinkle with freshly grated Parmesan and bake in the oven at 180 °C until cheese and surface begin to brown.
Fonduta: soak fontina cubes in milk for 120 minutes. In a bain-marie, mix the cheese cubes and butter with half the milk and the egg yolks for fifteen minutes to obtain a smooth thick cream (milk can be used to thin the cheese cream if necessary). The fonduta can be kept warm in a not too hot water bath.
Tip: It is best to use your favorite ham – then your dish will taste twice as good!
