Well they ain't.
I harvested about 12oz of the seedpods. That's quite a few. I blanched 4oz in boiling salted water like edamame. And they are really similar to the beloved pod but just too fibrous to crunch them up; the pods will split but the yield is measly for all the effort. The "beans?" were sweet, and vegetally reminiscent of broccoli. Overall, an unpleasant experience but educational.
The really small ones were tender and perfect. I will remember that. Harvest much much sooner...
I had one of Dave's brett biers while harvesting the pods. Tropical citrus and cherry. Pleasant in the warm evening sun.
