Triple Sec is a very, very essential cocktail ingredient. It's the liqueur of choice in many classic cocktails. Truly iconic in a sizzling Margarita, next to glorious bad boy tequila. Triple Sec is invented by the French in the 19th century, inspired by the Dutch (du-huh) who have been making orange liqueurs from the 17th century on. Distilled from dried, bitter Curaçao oranges and sweet oranges. It's crystal clear, it's strong, amazingly aromatic, full of delicious citrus and slightly sweet.
