Arab culture uses desserts to celebrate important occasions such as weddings, births, and achievements. Common dessert ingredients include homemade syrup made from sugar, water and lemon juice, as well as cheese and nuts. Baklava is a traditional dessert made of thin layers of phyllo dough filled with nuts and drizzled with syrup. Hummus and falafel are popular appetizers made from chickpeas, tahini, lemon juice and spices and served with pita bread. Mains such as makloubeh, a rice and meat dish served upside down, and couscous showcase ingredients adapted to each country while maintaining consistent flavors.
