A liqueur is a spirit sweetened and flavoured with fruit, herbs, spices, nuts or cream, and they are the backbone of countless cocktails as well as a lovely way to end a meal. You will know many by their names, from Cointreau and Kahlua to Chambord and Frangelico, but don’t forget the essentials like Triple Sec, Creme de Cacao and Blue Curacao that keep bartenders shaking. Whether you are after a late night sip or the missing ingredient for your next cocktail, you will find it here.
