Anyone have experience with sword beans? A little boy came to CG with a red bean and I just grew it for him. Now it has become a giant cluster with bean pods bigger than my palm. Problem is no on one seems to know when to harvest! I tried googling but gets different info. Some eats the pods so look for tender ones. But some says pods cannot be eaten, grow for beans inside must wait till the pods swell. Any ideas anyone?

It has very nice fragrant white flowers BTW :)/>

red sword bean grow to 30cm long. Maybe harvest just before the pod shows some sign of yellowing. or harvest young pods. After reading the article above some years back, it made me a bit worried, so I didn't eat the beans I grew. But according to some people I talked to, they have eaten it before. Need to cook them.

If anyone eaten before ,do tell us how to cook these beans.

Yikes! Beans with toxins.

From this article - http://www.e2121.com...wid=400

Toxic or Side Effects:
Mature seeds are toxic and must not be eaten unless they are extensively cooked (3 hours or more recommended) preferably using 2-3 changes of water, and the tough seed coats are removed.


Another article - http://www.feedipedia.org/node/326

In Madagascar the young green fruits and immature seeds of sword bean are used as a cooked vegetable (Bosch, 2004). Sword bean is eaten in Tanzania, where the Swahili expression ‘eating sword bean’ means ‘being happy’ (Bosch, 2004). Use of the fruits and immature seeds is also reported from Sri Lanka, India, Indonesia, China, Korea and Japan (Bosch, 2004). Sword bean is further planted as a forage and cover crop (Bosch, 2004). The ripe seeds can be eaten after cooking, but only after removing the seed-coat and several changes of water (Bosch, 2004).


I guess immature beans are ok to eat.

The more mature beans need extensive treatment. For mature beans I think most articles just direct you to remove bean coat and soak and cook and cook and cook till the toxic proteins denature. I saw an academic article too that says such heat treatment reduces about 50% of the toxic proteins so... I guess eat only a little and make sure it's cooked to death?


I personally would be a bit scared of eating it. But that's just me :lol:/>/>
