Robert Rogers, like every architect, wanted a martini. His edict was: “Let’s get together and talk gin!” So I took the abundant water present in his work as an invitation to, instead, do a gin highball, in fact my favorite one. In this version, you extract and incorporate the precious citrus oil in the lime’s skin, which, as Robert Frost wrote, makes all the difference.
Juice lime and set aside juice. Cut rind halves into thin strips and muddle in a mixing glass with gin. Add a dash of lime juice (1/4 to 1/2 oz.) and muddle further. In a tall highball glass half-filled with ice, pour tonic water carefully down the side so as to not lose carbonation. Fill to leave just enough room for the gin/lime mixture. Float the gin/lime mixture on top and garnish with a straw (carefully) and either two thin lime wheels or, as my dad did, some of the julienned rinds heaped atop. Serve striated as is, but inform your guest to mix it together before drinking. Serves one.
