Easiest and yummy dessert in the whole world :D
I bought a ready-made tart base, and cut the prunes, arrange them, throw in some sugar... into the oven.
Some fruits like prunes may contain a lot of water, when bake it oozes out a lot of juice. So the best is to pre-cook your tart base (Cuire à blanc, in french). Like this you can preserve the crispy base.
