Breton leek and mushroom tart

Breton leek and mushroom tart
This is a "tart" with a difference: the case is not made with pastry, but with a double layer of lightly buttered Breton galettes (buckwheat pancakes). The filling is made with shallots, sautéed mushrooms, leeks and cream.

You might have noticed that this recipe includes the key elements of Brittany's cuisine: buckwheat pancakes, butter and shallots.

Classic italian recipe (the name means "pull me up" or more poetically, "take me up to the sky"). It's similar to a charlotte in its structure: layers of flavoured biscuits between layers of smooth cream.
