SHAKE all ingredients with ice and strain into ice-filled glass.
Orange zest twist
Fresh orange is good for you. This has all of the flavour but few of the health benefits.
The creator of this cocktail is unknown but its name remembers a very different cocktail, equal parts of two herbicides, 2,4,5-T and 2,4-D that when mixed produced Herbicide Orange (HO). Better known as Agent Orange, this herbicide was used by the U.S. military as part of its herbicidal warfare program during the Vietnam War.
The origin of cocktail names is often forgotten and they sometimes commemorate sad as well as happy times. Some will enjoy this very tasty cocktail thinking about the codename for a dashing spy in a novel while others will reflect and remember a very different kind of Agent Orange.
