A shrub is an old-timey cocktail that has a mix of sweet and tart, coming from a fruit syrup or a vinegar base. They were popular in Colonial America, and began as a way of preserving fruit. When the base is lightly sweetened and stirred with cold water, a refreshing drink is crafted.
It becomes deliciously bracing when a spirit is added, in this case, mezcal. The Jorge Washington recipe comes from Josh Seaburg, bartender at Hilton Norfolk The Main [LINK]
