Normandy biscuits

Of all products except chocolate, knead the dough of medium consistency, form balls of the size of a large walnut from it, and from them - oval tubercles. Grease the tray with oil, sprinkle with flour and bake the product in it at medium temperature. Place the cooled tubercles tightly in a row on white paper and decorate with strips of chocolate. To do this, melt a little chocolate for a couple and mix it with butter. Pour the chocolate mass into a pastry bag and squeeze it into strips on the tubercles.
