For this cocktail, Hawksmoor NYC bartender Michelle Martinez was inspired by the ’90s-era French Martini. Small-batch Irish whiskey lends body to the drink, while sage and yuzu add a culinary edge. But the key to the recipe, says Hawksmoor bar manager Adam Montgomerie, is whip shaking the drink (shaking with a couple of ice cubes until the ice is fully integrated), which yields “a fluffy, tropical whiskey Sour.”
