Batter Recipes can be found Here.

Ficelle picarde is a dish of Picardy, northern France, consisting of a savory crêpe stuffed with Gruyère cheese, mushrooms, and ham.

Though now considered a classic Picardy dish, its origins appear based in  l'hôtel du Commerce, in Amiens-France, where chef, Marcel Lefèvre, created it in 1950 during a local fair. Some stories also state the dish originated in the era of Louis XIV.
