Flamiche means ‘cake’ in Flemish and this dish originates from northern France, near the border with Belgium. It is a puff-pastry crust filled with cheese and vegetables and resembles a quiche. The traditional French filling is leeks and cream. There is also a pizza-like version of flamiche, which is without the top crust of the pie. For a southern French twist, try the thin crusty pissaladière which is topped with anchovies, onions and olives.
