Freeze the passion fruit juice and use it to make slash ice. E.g. in this way: Pour juice into a sturdy freezer bag and let it solidify in the freezer. Then crush or crush the block in the bag. Mix a cocktail with the remaining ingredients and fill up with the slash ice.
Add 2 more ice cubes to the glass, then the slash ice will not melt as quickly. Serve with a drinking straw.
