For the house Espresso Martini at Bar Clacson in Los Angeles, general manager Dustin Newsome looked to aquavit for a more nuanced flavor. "We tested a half an ounce of aquavit (Krogstad), and it had the effect of drying it out on the palate, and hitting the mark we were going for," he says. From there, they add Leopold Fernet, which has "enough of a strong eucalyptus note in a barspoon measure to amplify the mint in the drink."
