There are very few drinks that I identify with summer more than Gin & Tonic. I’ve always loved the juniper-mellow Plymouth Gin from England, and I’m a fan of the Dorothy Parker Gin made down the road from my house. But the state of tonic water in the American market is grim. So I’ve been making my own. Making a concentrated syrup fragranced with assorted botanicals plus the all-important bark from the Cinchona tree (from which we get quinine) is a satisfying exercise, & the concentrate stores quite well so a batch can last you a while. All you need is a splash of the concentrate mixed into club soda or seltzer & you have a tonic water that’s worthy of your favorite gin.
