If you and I are as drooling as Nato's nutrition, and afraid of the smell of fermentation, or want children to fall in love with it, then try this method below~~
Put the avocado in a bowl and chop it into a sauce
Add fresh lemon juice to the butter and stir well
Mix the natto with chopsticks in a circular way, then pick it up with chopsticks until the long sticky silk is pulled out.
Pour the butter jam into the natto and mix well
Put in the onion section
Pour in soy sauce and yellow mustard and mix well.
Natto uses a small box of small boxes imported from Japan, which is usually bought by a supermarket. It usually contains a small packet of soy sauce and a small packet of yellow mustard.
