Here is a recipe. The Barmouth biscuit stopped and Foxes took over, then the french made a recipe as close as you'll ever get to it and here it is. Original Recipe Yield 6 dozen Ingredients. 9 tablespoons butter, softened 10 tablespoons white sugar 3 egg whites 1 1/2 teaspoons vanilla extract 1 1/2 cups all-purpose flour 6 (1 ounce) squares semisweet chocolate, melted Directions. Preheat the oven to 400 degrees F (200 degrees C). Lightly grease cookie sheets. In a medium bowl, cream together the butter and sugar until smooth. Beat in the egg whites one at a time until batter is light and fluffy. Stir in the vanilla. Mix in the flour just until blended. Dough will be a little stiff. Force through a pastry bag or cookie press with a medium star tip onto lightly buttered cookie sheets. Make each cookie about 3 inches long. Bake for about 10 minutes in the preheated oven, until straw-colored. When cool, dip one end of each cookie in melted chocolate and place on wax paper until chocolate hardens. Store in a cool place.
