What happens when an Old Fashioned meets a Pimm's Cup with a touch of Sazerac flair? A Pimm Bob!
Muddle tarragon sprigs, lemon slice, orange slice, strawberry, simple syrup, and Peychaud's bitters in a 12-oz. glass to release flavors. Fill glass with ice cubes. Add whiskey and chilled club soda; stir gently.
Lovely, balanced drink, will definitely make again!
