Sahlab is a traditional Egyptian drink that is popular in Cairo. It is made from a starchy powder derived from the tubers of the orchid plant. The powder is mixed with milk, sugar, and flavored with ingredients like cinnamon and nuts. Sahlab has a creamy and comforting texture, similar to a pudding. It is often enjoyed during the winter months as a warming beverage. In Cairo, you can find sahlab being sold by street vendors or in cafes.
