In France it is traditionally a ‘pièce montée’, a tall conical tower of choux buns stuck together with spun caramel. In the UK, we like a three-tiered cake to the recipe of the newly-wed’s choice. I tell my students that a typical British wedding cake is a rich fruit cake and that it was the custom to keep the top tier to eat when the first baby was born. They cannot believe that a cake can be kept without going mouldy. Because of the high butter content, it can be stored for 6-9 months and actually improves in flavour.
