The Wedding Coat is a modern cocktail that was first published in The Official Downton Abbey Cocktail Book by Lou Bustamante. Inspired by Carson's and Mrs. Hughes' wedding that takes place in a later season of the hit television show Downton Abbey, the recipe is a variation of the classic White Lady that also calls for gin as the base spirit, but it omits the original's frothy egg white and swaps out orange liqueur for tart crème de cassis.
Add gin, lemon juice, crème de cassis, and gum syrup to a shaker.
Fill shaker with cubed ice.
Shake for 15-20 seconds.
Using a Hawthorne and fine mesh strainer, strain into a coupe glass.
