Crepes can be layered with fillings and served as a crêpe gateau or a pancake stack. Spread firm fillings thinly to help keep the stack in shape, or use a metal ring mould or a loose-based tin to confine the crepes. (Make sure the crepes are cooked to the correct size for the tin.) Cook the batter as usual, then reduce the heat to cook the last crêpe so that it has a slightly paler colour. Place this one on the top of the stack and serve.
