I tried a batch of natto with black beans without success. Not sure what was the problem, maybe the starter was not fresh. I use instant pot on yogurt setting with reduced hours. I may try
soybean later. Strangely, soybeans are not easy to be found in grocery stores
At least in this part of the country, soybeans are not easily found anywhere. Not even in feed stores.
A couple years ago, I was interested in using soybeans as a protein source for a medium used to grow mushrooms such as shiitake. I totally struck out.
I hope you succeed eventually because I hope to try making natto using black beans.

Have you tried edamame in the frozen section? They are soy beans. We can find them in the grocery store. I live on the West Coast, so Asian culture may be more prominent here.
