In their new book, A Quick Drink: The Speed Rack Guide to Winning Cocktails for Any Mood, Lynnette Marrero and Ivy Mix (with Megan Krigbaum) spotlight the recipes of competitors and winners from their global bartending and fundraising competition, including Speed Rack USA winner Haley Traub. When Traub competed in 2018, she was prompted to create an Espresso Martini variation inspired by a loved one. She immediately thought of her grandmother, a three-time breast cancer survivor, and her mom's Black Forest trifle dessert. For her twist on the modern classic, she replaces vodka with bourbon, adds tart cherry juice, and complements the whiskey and espresso with vanilla syrup and chocolate shavings.
