Water chestnut. Famous from Xieng Khuang province these are starchy tubers of about 1 to 2 centimeters in diameter of dark grey color outside (a kind of root fruit). The inside is white like sweet potatoes. You can see them sold usually by farmers in markets in Laos. There is a Lao saying: "when you fall in love with a girl, you feel like you are eating mak haew (so sweet and coconut-milky taste that you don't want to stop eating)" (ngaam huk kun waan mun meuan dung kin haew).
