INTERNATIONAL NEGRONI WEEK. DAY 2. Patrik Tapper, exceptional bartender and master of the art of challenging the conventional, has really crossed a border: A warm Negroni inspired by Irish Coffee. Has he lost his mind? Not at all. This is pure brilliance. And this might be the coolest drink of the season. The Negroni Warmer: 20 ml Hernö Old Tom 20 ml Antica Formula 20 ml Carpano Botanic Bitter 20 ml water 20 ml sugar double cream orange zest or nutmeg Heat it until sugar has dissolved, pour into hot glass and top it with lightly whipped and fluffy double cream. Finish it off by grating some orange zest, or nutmeg if you prefer, on top of the drink.
