The French Martini helped to kick off the flavored Martini craze of the 1990s. Featuring vodka, pineapple juice and Chambord, the cocktail was first brought to prominence in the late-1980s when it debuted at the famous New York City restaurant Balthazar. The cocktail is emblematic of the era’s preference for fruity and sweet drinks, especially those with Martini in the name or anything appended with a ’Tini suffix (looking at you, Appletini).

The reason why this Martini is called a “French” Martini is the inclusion of Chambord black raspberry liqueur, which has been produced in France since the 17th century. The Chambord, along with the pineapple juice, adds rich fruit flavor to the drink. When shaken hard with plenty of ice, the pineapple juice—use the freshest you can find—creates a pleasantly creamy mouthfeel and a frothy head.
