Natto

This is my first time using Natto spores. I watched benefits videos and read several books in Natto making before I decided to make it. It can be pricey, so I wanted to get it right. The first batch not so hot...I only used one packs of starter. All recommendations said use more as the results would be much better and tastier Natto with more tendrils. I should have listened. The taste was not bad it was just under developed. So in the next batch I used three packets and voila! Perfect Natto (yeah) so other than the fact I had to use three x the amount it worked great on try two. I plan on oruchainh more spores and trying again with only one packet. I will let ya know. Until then happy fermentation experimenting.

Perfect Natto Spores

I've been making natto for a few weeks. I have made natto using spores from three different companies. When I use this natto starter it looks like it snowed on top of my natto and the neba neba strings are so thick that it's difficult to pull the natto beans apart. The difference between this product and others is significant and very visible. This is the freshest most easily activated spore I have found and it makes the tastiest natto! These spores are significantly better than any other I have used.

It worked!

I'd tried making natto three times before (with culture I bought elsewhere) and failed each time—it's a notoriously tricky ferment—but Cultures for Health's starter and instructions worked, and this morning I had fresh natto with miso rice and scallions. It was great!
