We ran across this recipe for a twist on a Salty Dog from the wonderful folks at Serious Eats. A Salty Dog is cocktail made of gin and grapefruit juice served in a highball glass with a salted rim. You probably know the cocktail because because a Salty Dog is a spin on a Greyhound, from which it derives its canine moniker (thanks Wikipedia). The only difference is a salted rim. Vodka may be used as a substitute for gin; nevertheless, it is historically a gin drink. But we like this rendition with vodka because as Serious Eats points out it’s more neutral flavor lets the bitter grapefruit juice and woodsy thyme flavors do the talking. Plus the salt rim makes for a tart, herbal and attention grabbing sip.
For the Thyme Simple Syrup: In a small saucepan, combine sugar and water. Stir over medium heat until sugar is dissolved. Remove from heat, add thyme, and allow to steep 15 minutes. Strain into airtight container. Thyme Simple Syrup can be refrigerated for up to 1 week.
For the Cocktail: Pour salt on a small saucer. Run lime wedge around the outer rim of a Collins glass and roll glass in salt to coat outside rim. Set aside.
Combine grapefruit juice, vodka, lime juice, and thyme syrup in cocktail shaker. Fill shaker with ice. Shake until well chilled, about 15 seconds. Fill salt-rimmed Collins glass with fresh ice and strain cocktail into glass. Garnish with thyme or lime if desired.
