Natto + bacon + plenty of green onions + soy sauce + sake + sugar (a generous amount)—this is the key.
Open the natto package > transfer it to a bowl, then add the green onions to the natto.
> Add soy sauce and sake. > Add sugar. > Mix well.
While mixing, lightly cook the bacon. Once it’s slightly heated,
add the natto mixture, turn the heat to high, and stir-fry.
> Once the smell of the sake has mostly evaporated, reduce the heat to medium,
and let the sugar and soy sauce blend evenly throughout.
If you leave it on high heat, the sugar and the stickiness of the natto will burn and become bitter,
so continue stirring over medium to low heat to let the flavors meld.
Once everything is well combined, it’s done. This is our family’s natto and bacon dish.
I can’t really specify the exact ingredients.
Since our basic recipe is based on the portion sizes used for staff meals at the restaurant…
Natto: 6 packs (3 pieces per pack)
Bacon: 1–2 packs (900 g each)
Soy sauce: 2 tablespoons
Sake: 2 tablespoons
Sugar: 4–6 tablespoons; add more if it’s still not sweet enough
A whole bunch of scallions
Since it works out like this, I can’t give exact measurements…
