Maraschino liqueur is a clear, cherry-flavored liqueur made from the Marasca cherry, a sour variety native to Croatia. The liqueur is produced by distilling the fermented juice of the cherries, along with their pits, which adds a unique almond flavor. It is often sweetened and can be enjoyed on its own or used in cocktails. This liqueur has a rich history, dating back to the 16th century in the Dalmatian region of Croatia. It is commonly used in classic cocktails, such as the Aviation and Last Word, and can also be drizzled over desserts for added flavor.
