Bougatsa is a custard-filled pastry popular throughout Greece. It is a semolina-based custard layered in-between sheets of flaky, buttery filo. This version is the 'lazy woman's' (homecooking in Greece is nearly always cooked by mom) because it cuts out the need to make a custard. Instead, a sweet milk/egg mixture is poured over baked filo sheets and baked further until the milk soaks the bottom layer of filo pastry, turning it dough-like and achieving a kind of 'custard'. The whole is served sprinkled with icing sugar and dusted liberally with cinnamon. We love it.
