Pastis is an anise-flavored liqueur that is popular in Marne-La-Vallée and other regions of France. It is made by diluting the liqueur with water, which turns it from a clear liquid to a cloudy and milky white color. Pastis has a strong licorice flavor and is often enjoyed as an aperitif before a meal. It is typically served over ice and is a refreshing and aromatic drink.
