Are "Black Beans" or "Black Turtle Beans" the same as "Black Soybeans?"
When I was at Whole Foods today--searching unsuccessfully for umboshi vinegar--I found black turtle beans in the bulk food section, but not black soybeans. I am familiar with various varieties--including Eden Organics--of black beans or black turtle beans, but have yet to run across black soybeans.
I don't believe they are the same. By the way, there is a Martins grocery store near my house that has both umeboshi vinegar and black soybeans (and black beans) in the organic section. Maybe try a Martins or Giant grocery store if there's one near you?
Black beans are definitely not the same as black soybeans. I don't know what black turtle beans are - that's a new one. I did have black edamame at a restaraunt and frankly, the "black" soybeans didn't look any different than regular green soybeans. Just a little dark near the crook of the bean, kind of like black eyed peas. Eden apparently has canned black soybeans, no salt added, just the soybeans, kombu, and water. http://www.edenfoods.com/store/product_info.php?cPath=21_32&products_id=103050
