Unripe passion fruit is too tart to eat. The riper the fruit, the better the sweet-tart taste. It makes a delicious treat simply scooped out of its skin with a spoon. The seeds are edible, although when using the fruit in recipes it is best to strain them out. The pulp of this fruit, like vanilla extract or grenadine, can be used as a flavoring in baking or for mixing cocktails.
