When the fruit is mature, you can rip off the skin, wash it and it looks like this. Used for bathing and washing dishes. If the fruit is young, you can boil soup with it.
I have never heard of such a thing ! Amazing... Do you bathe and wash the dishes with it BEFORE you make the soup or AFTER ? Just kidding... I saw those in some stores over time, but didn't know it was a fruit ! Really ? What does the fruit look like ?
