Thai iced tea or cha yen in Thailand is a drink made from strongly brewed black tea. This tea is sweetened with sugar and condensed milk and served chilled. Evaporated milk, coconut milk or whole milk is generally poured over the tea and ice before serving to add taste and creamy appearance. However, in Thailand, condensed milk and sugar are mixed with the tea before it is poured over ice and then topped with evaporated milk. In Thai restaurants worldwide, it is served in a tall glass, though in Thailand it is more typically poured over the crushed ice in a clear (or translucent) plastic cup.
