It Works!

My kids like natto a lot, but it feels bad to get all that packaging in the commercial natto for such a small amount so I was  excited to try this product. So glad it came with clear English instructions we’re looking forward to experimenting with different beans. We tried black soybeans first. I hope we can get the natto to be stickier.  It was satisfying  to be able to make it from scratch and for the kids to be able to eat as much as they liked, you can make a lot at once. We started out making a half quantity of the recipe with a one pound yield. If you follow the recipe you could make about 60 pounds of natto  with what you get in the package, and again I want to experiment with the method recipe, I’m fine making less and curious how to adjust it for stickiness and vary the beans.

Great quality natto starter

I have been making natto using this Japanese natto starter. It works fine with every batch. And this tiny bottle of starter lasts a long time. Will buy it again when the starter runs out.

1st Time & Success to Boot

As one previous reviewer had mentioned, I am lax on OCD sterilizing. (That said, I do clean the equipment etc and ensure food safety and sanitation)

Cutlures for Health did a good job by adding an instruction sheet in English. Plus the spores came in excellent condition and quality.

I am so happy that I can make Natto at home and use the ingredients I trust. Really adds a fun factor and saves me some money in the process.

Will definitely buy from Cultures for Health again!
