Cointreau is a clear, orange flavored liqueur developed in 1875 by Édouard Cointreau, son of one of the co-founding brothers of the distillery. In 1885 it became the first registered brand of triple sec, although the brand dropped “triple sec” from its name in early 20th century. It is made with both bitter and sweet orange peels which are macerated in neutral alcohol and then distilled. The only other ingredients are sugar and water. Suitable for any recipe calling for triple sec.
