The dessert baklava is traditionally made using layers of which type of pastry?

Baklava is a rich, sweet pastry made of layers of filo filled with chopped nuts and sweetened and held together with syrup or honey. It is characteristic of the cuisines of the former Ottoman Empire, and is also found in Central and West Asia.

Baklava is normally prepared in large pans. Many layers of filo dough, separated with melted butter and vegetable oil, are laid in the pan. A layer of chopped nuts—typically walnuts or pistachios, but hazelnuts are also sometimes used—is placed on top, then more layers of filo. Most recipes have multiple layers of filo and nuts, though some have only top and bottom pastry.

Before baking the dough is cut into regular pieces, often parallelograms (lozenge-shaped), triangles, diamonds or rectangles. After baking, a syrup, which may include honey, rosewater, or orange flower water is poured over the cooked baklava and allowed to soak in. Baklava is usually served at room temperature.
