Prepare your highball or other type glass by loading it half full of ice (at least 1/2 a cup). Crushed is best since it chills the drink quickly and lightens the taste. Build the ingredients with the alcohol first (except the dark rum) and then the juice and syrups. Stir all the ingredients with a straw (except dark rum). Slowly pour the dark rum on the surface in order to float it on the rest of the drink. As you consume the drink with a straw, the dark rum trickles down and gives a cool appearance.
