Thoroughly combine all ice cream ingredients using a bowl with a whisk or a blender. (A blender is much easier). Taste for sweetness and add as desired. This is an important step. Passionfruit is quite tart, but everyone has different taste buds. We like the tartness.
If you're in a hurry, you can stick the ice cream mix in the freezer to speed the process. Don't leave it too long! Otherwise, place in the refrigerator until it's very cold.
Following your manufacturers instructions, freeze the ice cream. My Cuisinart takes 20-25 minutes depending on how cold it starts out.
Scoop into serving dishes or glasses. Garnish as desired. Enjoy!
