1 oz dark rum
1/2 oz white rum
1 tsp Pernod® licorice liqueur
1/2 oz lemon juice
1 tsp grenadine syrup
100 ml Coca-Cola®

Funnel the rums, pernod, lemon juice and grenadine into one small cola bottle (185-200ml), roughly half-filled with cola. Briefly invert the bottle to mix the ingredients. Place in the center of a large glass (tankard, stein or british pint), and fill glass with broken ice. Add a straw to the bottle.
