Here is a quick how-to:

• Start with at least 5 passion fruit; set one aside. Cut 4 passion fruit in half and scoop the fruit out into a bowl; discard the skins. Add 1 cup water and about 2 tablespoons of sugar to a blender (more or less, to taste). Process for about 30 seconds.
• Add the passion fruit and pulse 2 or three times (no more than that). Use a fine-mesh sieve to strain the mixture into a pitcher. Add 3 more cups of water to the pitcher and stir well. Add ice if you wish. Pour into individual serving glasses and top seeds from the remaining passion fruit. Enjoy! Serves 4 to 6.
