Wild blueberry tart (Tarte aux brimbelles)

Tarte aux brimbelles is a traditional tart that's especially popular in Vosges and Belfort. The pastry dough is made with a combination of flour, butter, sugar, salt, egg yolks, and cold water, while the filling consists of wild blueberries, eggs, sugar, crème fraîche, and either crumbled cookies or semolina.

The dough is covered with plastic wrap and chilled. After an hour, it's rolled out and the blueberries are spread on top. The tart is baked for twenty minutes. A mixture of sugar, eggs, and crème fraîche is poured over the blueberries and the tart is baked for another twenty minutes before serving.
