In the process of preparation, the crepes should redden from below. From above, the surface of the crepes should become completely dry, without traces of liquid batter.

In this way, prepare all the crepes, putting them separately from each other so that they do not stick. In the center of each pancake let’s put 2 tablespoons of mushroom filling.
