Ladies and gentlemen, I believe we have our Thanksgiving beverage. One sip of the rum buck - light rum, lime juice and ginger ale - and my wife proclaimed "very nice." We may play around with ginger ale vs. ginger beer but we have a winner. My recipe came from The New York Bartender's Guide.
Bucks are a family of drinks combining ginger ale or beer with a citrus juice and a base liquor. The Moscow Mule, which uses vodka, is probably the most famous example. With gin, it's a Ginger Rogers.
