"Bostonians in the know are aware that any evening that snow falls (and sticks), they can head into No. 9 Park (or its sister bar in Fort Point, Drink) for a warm Tom and Jerry. This classic Christmastime tipple dates back to the early 1800s. No. 9 Park serves it right, by mixing a whipped batter of eggs, sugar, and spices with steamed milk, rum, and Cognac – in a traditional mug, of course." - Katie Faust Stryjewski
