Watermelon granita dark & stormy

This is a thirst-quenching and refreshing summer afternoon beverage. Don’t be tricked though as it does contain alcohol. Based on a Bermudan trademarked cocktail, Dark ‘n’ Stormy, made with Goslings Black Seal Rum, it is a drink for the sailors, made with ginger beer to help with sea-sickness and rum to keep you nice.
