Prepare the Strawberry Purée: In a blender, combine the strawberries and sugar (if using). Blend until smooth. If you prefer a chunkier texture, blend just until combined. Set aside.

Blend the Coconut Mixture: In the same blender, add the coconut cream, light rum, pineapple juice, and ice cubes. Blend until smooth and creamy.

Layer the Drink: In a tall glass, pour a generous layer of the strawberry purée at the bottom.

Add the Coconut Mixture: Carefully pour the coconut mixture over the strawberry purée. This will create a beautiful layered effect that resembles lava flowing.

Garnish: Drizzle a splash of grenadine over the top for added color and sweetness. You can also add fresh strawberry slices for decoration.

Serve: Insert a straw or a stirrer, and enjoy your tropical creation!
