Mazagran (also called café mazagran, formerly spelled masagran) is a cold, sweetened coffee drink that originated in algeria. portuguese versions may use espresso, lemon, mint and rum, and austrian versions are served with an ice cube and include rum. sometimes a fast version is achieved by pouring a previously sweetened espresso in a cup with ice cubes and a slice of lemon. mazagran has been described as "the original iced coffee".
