This powerful cocktail isn't for lightweights or the citrus-shy.
Rub the rim of a chilled cocktail glass with a tangerine wedge. Spoon a thin layer of sugar onto a small plate and gently twist the rim in the sugar to coat.
Put remaining ingredients in a cocktail shaker with ice, then shake for 15 seconds. Strain into glass and garnish with a twist.
