how do i tell if my passion vine fruits are edible?

Answer 1

This site tells about Passion Fruit (and there's a drawing).

http://www.crfg.org/pubs/ff/passionfruit.html

It says (in part):

"Harvest: The fruit will quickly turn from green to deep purple (or yellow) when ripe and then fall to the ground within a few days. They can either be picked when they change color or gathered from the ground each day. To store passion fruit, wash and dry them gently and place them in bags. They should last 2 to 3 weeks at 50° F. The fruit is sweetest when slightly shriveled. Both the fruit and the juice freeze well. The flavor of passion fruit blends well with citrus and many other fruit flavors, and is quickly appreciated by many people as they become familiar with it."
