“Kitschy blue cocktails had their heyday in the eighties, but like all things vintage, have made a comeback. Bartender John deBary is credited with bringing back the blue in modern times, at the respectable New York speakeasy bar PDT (Please Don’t Tell). deBary created the festive tiki drink for his friend and PDT regular Jacob Briars, and named it after another PDT bartender, Sean Hoard, whose nickname is “Sharky”. The drink is based on butter-infused rum, using a technique known as fat-washing, also invented at PDT, and features a riot of flavors including hazelnut and pineapple.”
