From the Tujague's Cookbook - this is perfect for cooler weather months. 

Philip Guichet’s Grasshopper cocktail achieved international fame, having placed second in the 1918 New York competition. His Whiskey Punch never received that attention, despite winning first place in the 1956 Early Times National Mixed-Drink Competition. Philip preserved a copy of his recipe behind a framed group of photos from the event, discovered in Tujague’s third-floor attic. In 2015, for the first time in the twenty-first century, Philip Guichet’s prize winning Whiskey Punch was served again at Tujague’s.
