Flan Normand is a flaky pastry -based (pâte-sablée) variant of the apple tart made in Normandy which is essentially a creamy egg custard tart topped with apples, sliced almonds and sugar and baked until the topping is slightly caramelised. It is also known as Normandy Tart or Tarte Normande

This is a dish made in one of two sizes, one of which is just under one third of a metre (approximately one foot) in diameter, and a smaller variety, between a half and one third the diameter of the larger type.

The key difference from other similar tartes are that other egg-custard tarts (a dish common in the United Kingdom) do not have the apple and almond topping (and tend to be made with a short crust pastry).

Another classic egg custard dish, crème brûlée tends to be prepred and served in a ramekin without any pastry or fruit topping and is given a fully caramelised top (by grilling a sugar topping until it is a hard, solid glaze).

Other apple tarts that probably originate in Normandy include a variety which, instead of egg-custard, has a layer of almond paste, or almond and apple paste, or frangipane almond pastry all topped with a pattern of semi-circular apple slices (some are decorated with a pastry lattice and most are made with short crust pastry).

In the UK, the French boulangerie chain Paul (www.paul.fr) sells Flan Normand (only in the larger size in the UK) under this product name (and with apparently close adherence to the tradional 19th century recipe, where the topping and overall appearance is 'rustic') but many UK supermarkets (including Tesco) sell product with labelling entitled 'French Apple Tart' with no precise details provided concerning the regional source or historic provenance of the recipe, which in the case of the supermaket products is typically of the 'apple and almond paste below apple slices' variety, without any egg-custard or semi-caramelisation.
