How to make:
SHAKE first three ingredients with ice and fine strain into chilled glass. TOP with champagne.
Orange zest twist (discarded)
A subtle hint of biscuity champagne shines through this very quaffable drink.
There are many versions of this classic cocktail but I have taken this one from Dale DeGroff's 2008 'The Essential Cocktail' where Dale credits this recipe to the Ritz Bar Paris circa 1936.
