Adapted from the classic Mr. Boston Official Bartender's Guide, our Grand Royal is a dangerously drinkable concoction that is both luxurious and refreshing. The heady floral notes of gin are cut by the tartness of the citrus and rounded out by the sugar. Not overly sweet, the cherry liqueur adds a fruity note at the end while the cream lends richness, giving the drink a velvety-smooth mouth feel. The whole thing is then topped off with the all-important "fizz," which wakes up the drink and gives it legs to stand on.
