2 oz. liquor of choice (rum/tequila/vodka/etc) 1 oz. crime juice 4 oz. ginger beer
For bonus points, serve that shit in a champagne glass, but you can throw it on the rocks Moscow Mule style.
For double points, make your own ginger beer, and for triple points carbonate the whole thing in a keg.
Crime Juice:
1 liter cranberry juice 20 grams citric acid 2o grams malic acid
