**the date tarts should be thin but solid enough to contain the filling.
1. Grind the nuts and the dates in a blender, then add salt.
2. Place the mixture in individual baking molds, level up and put away in the fridge for 30 minutes.
3. Take the baking molds out of the fridge and fill with a mix of yoghurt and vanillin. Decorate with fresh berries.
