The crepes with mushrooms can be prepared in advance and reheated before serving, or you can freeze them in a suitable container. In addition, when making the crepe batter, if you have trouble digesting milk you can replace it with water. As for the quantities, bear in mind that with a half-litre of milk you will get about 30 crepes with a diameter of about 15 cm.

Crepes are a very old dish dating back to the Middle Ages, and are a symbol of French cuisine traditionally served at Candlemas: when they were flipped over in the pan it was customary to make a wish.
