Lava Flow Cocktail 1 oz. coconut rum 1 oz. light rum 1/2 banana 2 oz. pineapple juice 2 oz. coconut cream 2 oz. frozen strawberries Blend the strawberries and rums separately from the other ingredients. Pour the strawberry mix or the puree to the bottom of a large glass (a collins or hurricane glass). Then add the blender ingredients, or as it’s often done, reverse and pour the strawberry mix on top. The red strawberry mix swirls in the drink, simulating a lava flow.
