These fruit are growing on some lattice on our fence. The plant is on the neighbour's side so I don't know what it is. Does anyone know?
I am surprised that you could eat it! It's a pest in my book, I put it out every time I see it. When those pods open the seed flies every where! It will be an ongoing job for me as it is growing on next door fence & I often see it as I walk our block!
When I was growing up there was a persistent urban myth that McDonalds used choko in its apple pies and just added apple flavouring as they were dirt cheap and had zero flavour.
This is a good guide @AndreaNg - http://www.wikihow.com/Select-and-Use-Chokos-(Chayote-Squash)
It tells you how to select them and how to cook them.
