Curaçao

Curaçao is a liqueur flavored with the dried peel of the bitter orange variety laraha, a citrus fruit grown on the Caribbean island of Curaçao. Curaçao can be sold in numerous forms, though the most common are the orange-hued dry curaçao and blue curaçao, which is dyed bright blue. It is not known who developed the first curaçao liqueur, and when. The Dutch West Indies Company took possession of Curaçao in 1634. The Bols distillery, founded in 1575 in Amsterdam, had shares in both the West and East India Companies to guarantee its access to spices required for their distilled drinks. According to the early nineteenth-century French culinary chronicler Alexandre Grimod de la Reynière, curaçao originated in Flanders, and proximity to the province of Holland gave distillers easy access to the necessary peels (since Curaçao was a Dutch colony at the time).
