Slap the mint leaves and place them in a collins glass. In a Boston shaker filled 3/4 with bar ice, add whiskey, Raki, simple syrups and tea. In collins glass, add a few large ice cubes; strain the cocktail over the ice. Dot cocktail with Peychaud Bitters; add mineral water for a lift. Garnish with fresh mint at the top of the glass, slapping mint lightly to release its oils. Recipe courtesy of Warren Bobrow, author of Bitters and Shrub Syrup Cocktails.
