Firts the soy beans (daizu/大豆 in Japanese).
Use a large vessel as you will need 2 to 3 times as much water: 1 volume of soy beans + 2~3 volumes of water.
Make an effort touse clean cold water!

Next you must steam the soy beans (preferably the slow way) for three hours to get them soft, otherwise they will not ferment. You may use a pressure cooker, but you will have to expperiment!

Important point: From now on, especially, make sure that all vessels and utensils you use are properly boiled in hot water first to kill all germs, or you will end with a yeast/germ/mold battlefield!
Use a large metal shallow vessel for even wieght and spread.
Transfer the steamed soybeans on eat as shown in above picture.

Now, for the all-important “sneaky” trick!
The beauty of it is that from the second batch you will use your own batto! Friends with some knowledge in yoghurt or Japanese sake fermentation will easily understand!
Drop a few grains of natto bought at the market in half a cup of water/ 100~cc/ml. (use high quality non-gaseous mineral water!)
After stirring 2 or 3 times, the water should start turning whitish. This is your yeast/fermentation starter!

Cover/wrap the whole with cellophane paper. Punch small holes (about 20) with a toothpick to allow ventilation.

Now, the whole important thing: the temperature!
Like for Japanese Rice fermentation, it must stay between 30 and 40 degrees Celsius. There are many ways to do it if you do not have the right room for it: use a hot water bottle (above) put nearby and cover it with a blanket, or put it under a heated blanket….

keep checking the temperature!

Here is the finished product!
True to tell, home-made natto might not as “sticky” as natto bought in markets, but this is still true natto.
Actually, the lack of “stickiness” might be be a blessing for some!

Keep in mind this is a true food, especially for vegans and vegetarians who are in more need of nutrients than omnivores!

Natto: Make-It-Yourself Recipe/ Recette de natto maison ! (15)

D’abord les graines de soja (daizu/大豆 en japonais). Utilisez aussi un récipient assez large car il vous faudra 2 à trois fois plus d’eau que de graines. Utiliser de l’eau pure de préférence pour cette recette. Faites les tremper toute une nuit.

Ensuite il faudra les faire cuire à la vapeur (lentement si possible) pendant trois heures pour les ramollir. Cette étape est essentielle car sinon la fermentation n’aurait pas lieu.. tout comme cette odeur caractéristique. Un autocuiseur fait l’affaire, mais vous pouvez essayer différentes techniques si vous avez d’autres idées.

Important: C’est à partir de là qu’il faudra vous assurez que vos instruments sont stérilisés, vous pouvez les faire bouillir pour cela, dans de l’eau chaude. Dans le cas inverse vous vous trouverez surtout avec un champ de bataille où les bactéries affrontent la moisissure. Utilisez un récipient peu profond, en métal pour les disperser. Mettez les haricots cuits vapeur tel que montré ci-dessus. L’odeur va commencer à devenir prenante alors choisissez le lieu de fabrication avec sagacité !

Natto: Make-It-Yourself Recipe/ Recette de natto maison ! (19)

Voilà le temps de la petite “astuce”. Toute la beauté de celle-ci est que vous pourrez utiliser à nouveau les natto du premier lot pour créer le second. Comme le yaourt on vous dit ! Mettez quelques graines de natto achetées dans un récipient a demi rempli (100ml à peu près) d’eau toujours autant pure que possible. Après avoir agité la solution deux ou trois fois, vote mélange devrait devenir un peu trouble, c’est donc votre fermentation qui prend consistance !

Natto: Make-It-Yourself Recipe/ Recette de natto maison ! (20)

Mettez cette agent fermenté soigneusem*nt avec les autres graines cuites vapeur de manière uniforme.

Le plus important désormais : La température. Comme pour faire fermenter du riz, on doit être entre 30 et 40 degrés. Il y a plusieurs solutions pour ça si vous n’avez pas de pièce adaptée : Couvrir d’une bouteille remplie d’eau chaude, recouverte d’une couverture, mettre sous une couverture chauffante, etc… laissez faire votre imagination.

Natto: Make-It-Yourself Recipe/ Recette de natto maison ! (24)
