Balmoral Dessert Biscuits. (From H.M. the Queen's baker, Balmoral Castle. 1856.)
These are not thicker than Passover Cakes, and very "short." 1 lb. of flour, 1 oz. butter, 4 volkes of eggs, only 2 whites. Mix the above into a stiff paste; roll out very thin, and cut into round shapes, size of top of a teacup, with wavy-edge pastry cutter. Bake in a slow oven. The biscuits should be quite thin, blistered all over, but not browned, and not pricked. The blisters are the same colour as the biscuits, not darker.
They are only good when quite fresh from the oven.
