Autumn Grape Silver Sour Cocktail

"Autumn grape pickle twist on McDonough's 1883 recipe for a silver sour cocktail. A silver sour was a fancy sour cocktail using egg white to create a luxurious creamy texture. This version uses a grape shrub syrup spiced with pink pepper and cinnamon paired with an oaked gin and a spicy honey liqueur, honey syrup and egg white. Garnished with a single red grape, a nasturtium flower and a dusting of cinnamon for a warming grape, honey and gin Autumn cocktail."
