Curaçao syrup is an ingredient used in the preparation of cocktails and alcoholic drinks. It is made from a Curaçao liqueur, an alcoholic drink produced from bitter orange bark from the island of Curaçao, in the Dutch Antilles. Curaçao syrup has a soft and fruity orange flavor, which goes well with many other ingredients. It is often used in cocktails such as Blue Lagoon and Margarita.
