Gypsy Tart vs Mousse au Chocolat: Velvety French Chocolate Delight

Both desserts rely on butter and vigorous whisking, yet they put them to very different uses. In the Gypsy Tart, cold butter is rubbed into flour for a golden, blind-baked pastry case, while the filling gains its lift from evaporated milk and dark brown sugar whisked for fifteen minutes until fluffy, then baked briefly to a gentle wobble with a slightly tacky top. The mousse instead melts butter into 70% dark chocolate for a glossy base, folds in stiffly beaten egg whites and sets in the fridge rather than the oven. The result pits deep brown-sugar sweetness against light, airy, intensely chocolatey richness.
