151. Gin Cocktail

My interpretation:
   2 oz Castle & Key London Dry
   1 dash Angostura bitters

Stir in mixing-glass half-full of cracked ice, strain into cocktail glass; twist lemon peel, serve. — This traditional gin cocktail recipe goes back to Jack’s Manual 1908. By contrast, Straub calls for “1 or 2” dashes of Orange bitters, no mention of lemon peel.
