While there is no official category for ostentatiously garnished classics, we refer to them as “chain- reaction drinks.” One hits the bar and, soon, everyone’s drinking one. The Pimm’s Cup—a simple mix of Pimm’s No. 1 liqueur and ginger ale, garnished with abandon—is one of those drinks. Here we replace ginger ale with American lager and then garnish the drink with a bounty of fresh winter herbs, apples, and cranberries for a headturning holiday take on the classic summertime cooler.
