For 4 servings, gather these items:
- 1 cup passionfruit puree or juice
- 1 bottle 750 ml chilled Prosecco
- 4 tablespoons simple syrup
- Ice cubes optional
- Passionfruit seeds or slices for garnish
Fresh passionfruit gives the best flavor, but store-bought puree works too. Choose a dry Prosecco to balance the fruit's sweetness.
