Pisco Sour Blueberry Shrub
"Seasonal pickle twist on vintage Peruvian pisco sour recipes such as that published by S.E. Ledesma (1903: 32) using a spiced blueberry shrub syrup and honey syrup instead of citrus and sugar, Peruvian pisco brandy, real free range organic egg white, Peruvian bitters, garnished with fresh thyme and bitters."
