Layers of crisp golden filo pastry or delicate semolina cake, soaked in aromatic orange blossom honey syrup and crowned with crushed pistachios.
Stir the semolina, the first sugar, melted butter, yogurt, and baking powder into a thick batter and rest for 15 minutes.
Boil the syrup sugar, water, and lemon juice for 10 minutes and set aside to cool.
Spread the batter into a buttered square pan, smooth the top, and score into diamonds with an oiled knife.
Bake at 180C for 30 to 35 minutes until golden and springy to the touch.
Pour the cooled syrup evenly over the hot basbousa and let it absorb for at least 1 hour before cutting.
