2 oz Gin
¾ oz fresh lemon juice
¾ oz honey syrup (use equal parts honey and warm water)

Shake ingredients together with ice, strain into a chilled coup or lowball, garnish with a twist of lemon

The honey and lemon were originally meant to mask the funk of this prohibition-era, bathtub-gin cocktail, but it turns out they're also just good ideas. More history: http://www.pbs.org/food/recipes/bees-knees-cocktail/
