Truffle crepes

Preparation:

Preparation: Prepare the crepes: beat the egg with the salt in a bowl, add the sieved flour and a few tablespoons of cold milk. Mix to obtain a mixture without lumps, then dilute it with the rest of the milk. Put a pan greased with butter on the heat, pour in about a quarter of the mixture and brown the crepe first on one side and then on the other. Greasing the pan each time, prepare 3 other crepes in the same way. Spread a slice of ham and one of fontina cheese on each one and complete with a few slices of truffle. Roll up the crepes so that they form a double cylinder, tie them at both ends, arrange them in a buttered baking dish and bake them at 190 degrees for around ten minutes after sprinkling them with knobs of butter. Serve the crepes warm but not hot.
