Mitoku Traditional Natto Spores
Product Review (submitted on December 6, 2013):
Alas I did not have good results, and I think I know why. This baby likes it warm, and I live in chilly New England. Where am I going to get something warm that's big enough for all those beans? The lowest setting on my oven is TOO warm. So I put them on a heating pad that one uses for aquariums with lizards, but that was not enough. I ended up with smelly, moldy beans. I really think that the directions should start one off with a smaller batch. As it is, the recipe calls for a very large amount, and that's not good for starters, when one is still experimenting. There's no doubt that the quality is good, because I did see that stringy web stuff, and it smelled like natto. I just have to figure out how to keep them at the warm temperature they like, and then I think all will be well. I know the Japanese have special natto units to keep them warm, and that may be the best way to go, if you can afford it. I gave value and quality 5 stars here because it's clear to me that the problem is my cold kitchen, and not the culture itself. I guess I'll just have to move to the Florida keys.
