The main ingredient in a traditional baklava is phyllo dough. This delicate, thin pastry is layered with chopped nuts, such as walnuts, pistachios, or almonds, and sweetened with honey or syrup. The layers of phyllo are brushed with melted butter or oil to achieve a crispy and flaky texture when baked. Baklava, originally from the Middle Eastern and Mediterranean regions, has become popular worldwide and is often served during festive occasions. Its combination of flavors and textures, paired with the sweetness of syrup, makes it a beloved dessert.
