Just made these with frozen sweet dark cherries and they're great. They'd be just as good without alcohol...(ok, maybe I'd miss the gin this Friday evening...) I think they'd be amazing with fresh sour cherries and a little more simple syrup.
Cherry-Lime Gin Rickey
From EatingWell: May/June 2012
Gin, seltzer, bitters, lime juice, cherries and simple syrup combine for a truly refreshing cocktail in this gin rickey recipe. For a nonalcoholic rickey, omit the gin and add a little more seltzer.
