#1 Vietnamese Iced Coffee

Mazagran, a cold, sweetened coffee beverage that originated in Algeria circa 1840, has been described as "the original iced coffee". It was prepared with coffee syrup and cold water. Frozen coffee beverages, similar to slush, are documented in the 19th century, often called "café frappé (à la glace)". Similar is the Italian granita al caffè. **Coffee brewed then chilled with ice, called "iced coffee", appears in menus and recipes in the late 19th century.
