Mazagran
Mazagran 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". It has been stated that the drink's name probably originated from a fortress named Mazagran in a costal town called Mostaganem north west of, Algeria which in 1837 through the Treaty of Tafna was granted to France. At the Mazagran fortress French colonial troops consumed the beverage, which was prepared with coffee syrup and cold water. It has also been stated that the drink's name and invention may have originated from French Foreign Legion soldiers who, during the time of the siege of Mazagran, Algeria during the 1840 war, used water in their coffee in the absence of milk or brandy and drank the beverage cold to counter the heat. Furthermore, French colonial troops near Mazagran were served a beverage prepared with coffee syrup and water. When the soldiers returned to Paris, they suggested to cafés to serve the beverage and the notion of it being served in tall glasses. Upon this introduction, the beverage was named café mazagran. In France, coffee served in glasses is referred to as "mazagrin". Mazagran is prepared with strong, hot coffee that is poured over ice, and it is typically served in a narrow, tall glass. It has also been described as "coffee taken with water instead of milk", in which coffee is served in a tall glass along with a separate container of water to mix in with the coffee.
