However I've never really considered making natto, not sure why, I love it and eat it sometimes. (And I would love for my kids to like it, any ideas how to serve it up sweet for them?)
Today I stumbled onto this video, and it looks so easy! Pretty much just like making yogurt! Although I think I'll use my dehydrator to maintain the temperature, and I don't think I need to double tent it and put it in a bag.
I'll keep you all updated! Then I'll share!
