Harvest the immature seeds while they are still white. To do this,
twist off the pod, then slit it open with your thumb-nail. Scrape the inside with a spoon to remove the seeds with the winged shells intact and as much
of the soft white flesh as possible. Place seeds and flesh in a strainer
and wash well to remove the sticky, bitter film.
At this point the seeds can be prepared in the same
way as green peas, mixed with rice like beans, or roasted or fried
in oil to give a taste like sweet groundnuts.
