1 pinch of sugar
1 slice of lemon
1 1/2 oz of Frangelico hazelnut liqueur (or Hazelnut Liqueur)
1 dash of grand marnier orange liqueur (or orange liqueur)
Pour the frangelico into a shot glass. Place a slice of lemon over the glass, pour some sugar over the lemon, then cover with a dash of Grand Marnier (so the sugar becomes sticky and partially dissolves). Drink, then bite the lemon.
