A White Slussian is another variant on the popular White Russian cocktail. Owing to this, the ingredients vary greatly but the defining feature for this particular variant being that the drink is mixed then ice added and to finish it is mixed in a blender until a "slush" like consistency is achieved. Hence, "White Slussian"
