Also known as a "Gin and Bitters," this drink is incredibly simple. Basically a combination of gin and Angostura bitters, it is nonetheless a great little drink. I made this with a recent acquisition, Hendrick's Gin, and found it to be smooth, almost like slightly botanic-tasting water. All in all, it is almost painfully sophisticated and incredibly yum.
