One of my vegetable garden experiments was the Black Calypso Bush Bean from The Cottage Gardener. The seedlings that were not attacked by squirrels yielded a fair amount of seed pods, but I wasn't sure when to pick them. When they first started to develop, I ate them as I would a sugar snap pea and they were delicious, but they were green and did not resemble the black and white seeds I planted. Patiently I waited for them to mature even further and I finally got the beans pictured here. Unfortunately some were left on the vine a little too long. But at this stage, these ones were a little tougher to eat and I didn't know what to do with them.
I went to the Cottage Gardener site (which I should have done in the first place, duh!) and the description recommended using them for baking or soup making. Now I don't quite have enough for a hearty soup, but I may throw them in to one with other beans to see how they taste!
