The Gibson cocktail is a classic combination of gin and vermouth. It’s most commonly complimented with a pickled onion, something we don’t see too often in cocktails.
Place 2-3 ice cubes in a Boston shaker or equivalent cocktail shaker.
Add 2 1/2 ounces of gin.
Add 1/2 ounce of dry vermouth.
Shake until the shaker is cold to the touch.
Pour into a Martini glass and add a pickled onion as pictured.
For an alternative to this drink, try a Dirty Martini
