How to Make It
In a cocktail shaker, combine the gin, Raspberry Syrup, lime juice, Batavia-Arrack, amaro and cayenne pepper. Fill the shaker with ice cubes and shake well. Strain into a chilled, crushed-ice-filled tiki mug or tall glass. Garnish with the mint sprig and raspberries.
Raspberry Syrup: In a medium saucepan, combine 4 ounces water with 3/4 cup superfine sugar and 1 1/2 cups raspberries. Cook over low heat for 15 minutes, smashing the raspberries. Remove from the heat and let stand for 30 minutes. Strain the syrup into a jar, cover and refrigerate for up to 4 days. Makes about 8 ounces.
