Orange curaçao is a sweetened orange liqueur, flavored mainly with the dried peel of the laraha — a bitter orange grown on the Caribbean island of Curaçao.
Orange liqueurs differ in three things at once — sweetness, strength and whether they color the drink — so plan to correct at least one. Sweeten with syrup half a barspoon at a time, and if the bottle is weaker, top the strength back up with neutral spirit. Orange juice is not a substitute at any measure.
Triple sec
Made on neutral spirit and usually drier and lighter, with no brandy weight underneath. In a Sidecar it leaves the drink sharper and shorter on body.
Brandy-based orange liqueurs
"Grand Marnier" and its kind stand on aged brandy, which makes them richer and closer in weight. It is the nearest thing on most shelves, and it brings a little more sweetness with it.
The liqueur itself is clear: blue, orange or green curaçao is coloring rather than a separate flavor.
