Perhaps you've noticed that the word "shrub" has recently been sprouting up on cocktail menus across the country. OK, we apologize for the bad pun, but in all seriousness, shrubs are tart syrups made from fruit, sugar and vinegar, and they're quickly becoming a favorite of bartenders.
The ingredient's history goes back hundreds of years, when it was employed as a method of preserving fresh fruits in colonial America, but its balance of sweet and sour is a perfect foil for spirits--and it can be used in a surprisingly wide range of drinks.
At their most basic, shrubs are extremely simple to prepare: Just heat up sugar and vinegar until the former dissolves, pour over some cut-up fruit and let stand for a while. That was the lesson we learned from Scott Dolich and Nate Smith, the chef and head bartender, respectively, of Park Kitchen in Portland, Ore., during their session about using culinary techniques behind the bar at this year's Portland Cocktail Week. Smith's Pear Shrub couldn't be easier (and the leftover pears make a gourmet breakfast with granola and yogurt), but the complex Pear With Me cocktail it goes into is deliciously full of flavor.
Fruits with a lot of acid are another good candidate for shrubs. New York watering hole Saxon & Parole uses tangerine peels and apple cider vinegar for its Tangerine Shrub, which it features in the bubbly and refreshing Tangerine Collins.
So what are you waiting for? It's time to go out and buy some vinegar.
