Traditionally made using the dried peel of the small Curacao orange, named after the island of Curacao in the Caribbean, Curacao liqueurs can be clear, blue or orange. The colours are purely decorative, but the bitter orange flavours are very similar. The Curacao fruits are sliced and macerated in fine neutral spirit to extract the flavours. Once the blend has been enhanced with sugar and brandy, it is then left to marry for several weeks to develop its full flavour. Rarely consumed neat, De Kuyper Orange Curacao is a vital ingredient for various eye-catching cocktails.source: in-the-spirit-shop.co.uk
