You may be familiar with this Thai iced tea, it's the milky, orange drink that's often served in Thai restaurants in the United States and Europe. Inside of the typical Thai iced tea you'll find black tea brewed with boiling water using a cloth strainer, plus some sweetened, condensed milk, served over ice with sugar and a little evaporated milk on top. These days the reddish, orange color is the product of food coloring, though traditionally it may have come from another natural source. If you prefer your Cha Yen without extra sugar, you can ask for it "mai waan," which means "not sweet." You'll still get a little sweetness from the condensed milk but at least you won't get the scoop of sugar on top of that!
