Use chickpeas on a sheet of parchment paper to prevent the pastry from puffing up.
Second batch: almonds and blueberries
Meanwhile, place the blueberries in a bowl, fill it with water, and swish them around with your hands to rinse them. Remove the strainer and pat the blueberries dry with a kitchen towel.
Once the shortcrust pastry has been pre-baked, remove it from the oven and sprinkle the bottom with ground almonds.
Next, spread the blueberries over the bottom of the tart. For a nice finish, try to distribute the blueberries as evenly as possible.
Put the pie back in the oven for 15 minutes.
Filling and final baking
Meanwhile, prepare the filling: crack the eggs into a bowl, add the sugar, and whisk them together. Add the crème fraîche and mix well until smooth. Set aside in the refrigerator.
Once the first baking is done, remove the tart from the oven and pour the custard over the blueberries so that the entire tart is well covered.
Return it to the oven and bake for another 15 minutes. You can enjoy this Pyrenean blueberry tart while it’s still warm with a scoop of ice cream, or let it cool before serving—it’s sure to be a hit either way!
