Gin Sling Recipe
This is a late-19th-century sling recipe that the author served for years at the Rainbow Room with great success. The ladies from the photo-editing department of the Associated Press next door were especially fond of this recipe. The cocktail was first described in print as a bittered sling. Before the addition of bitters, a sling was spirits, sugar water and sometimes lemon.

Ingredients
1 1/2 oz. gin
1 oz. sweet vermouth
3/4 oz. fresh lemon juice
1 oz. simple syrup
1 dash Angostura bitters
Ice as needed
Soda water as needed
Lemon-peel spiral for garnish
Directions
In a cocktail shaker, combine the gin, vermouth, lemon juice, simple syrup, bitters and ice. Shake, then strain over ice into a collins glass. Top with soda water. Garnish with a lemon-peel spiral. Serves 1.
