For the mango tart, knead the flour with butter, sugar and the egg to a smooth dough. Then flatten the dough, wrap it in plastic wrap and let it rest in the refrigerator for about 30 minutes. Then preheat the oven to 180 degrees.
Butter the springform pan well. Roll out the dough on a lightly floured work surface to a thickness of about 5 mm. Line the springform pan with the dough and raise a rim. Place a sheet of baking paper on top of the dough and fill with rice or baking peas.
Put the springform pan into the preheated oven and bake for about 20 minutes at 180 degrees. Then remove the baking peas or rice and the baking paper.
Bake the base again for about 20 minutes at 180 degrees. Then let the base cool very well in the springform pan. Melt the white chocolate in a water bath and then pour it on the cake base.
