Sharks Fin Melon

Bit the bullet and cut open the Sharks Fin melon today, expecting to find a dried up husk after three years sitting on the window sill.
Far from it, it was full of moisture and the flesh is solid around the edge. Loads of seeds harvested which once I dry out a bit I will see if they germinate.
Has anyone actually eaten a sharksfin melon? 

I tried a bit raw and it was fairly tasteless with a strange aftertaste. Apparently in sharksfin melon soup you boil it for three hours with pork or chicken and its enjoyed because of its fibrous texture rather than its taste. I just wounder whether the bitter aftertaste would disappear after cooking?

I may give it a try in soup with a bit of chicken stock as it is esteemed by some.

 It will also be interesting to see if the seeds germinate. I imagine the black ones are the ripe ones?
