Flaky, all-butter golden pastry filled with a delicately spiced sweet filling, baked until crisp and aromatic.
Simmer the sugar, water, and lemon juice for 10 minutes; stir in the orange blossom water and cool completely.
Mix the chopped pistachios with the cinnamon.
Brush a rectangular tray with butter; layer half the phyllo sheets, buttering each, spread the pistachio filling, then layer the rest, buttering each sheet.
Score the top layers into diamond or square pieces with a sharp knife, cutting through to the filling.
Bake at 160C for 50-60 minutes until deep golden and crisp.
Pour the cooled syrup evenly over the hot baklava; let it soak for several hours before serving.
