Lime zest twist
Apricot brandy replaces triple sec in what otherwise follows the same recipe to a classic Margarita.
This twist in the Margarita was published in W. J. Tarling's 1937 'Cafe Royal Cocktail Book', 16 years before the first written reference to a Margarita. He also lists another drink called a Picador which is identical to the later Margarita.
