The masataka swizzle popped up in the bartenders travelling book, a hand-written manual traveling from bar to bar across the world, containing contributions from every mixologist who gets their hands on it. This recipe is from stanislav vadrna at paparazzi in bratislava, slovakia. Named for masataka taketsuru, the father of japanese whiskey, the masataka swizzle is a beautifully smooth cocktail with rich, nutty flavors. The garnish of bitters is a nice touch at first you smell them as you sip, and their spices melt gracefully into the drink.
