Recipe Notes

Konbucha: This is not Kombucha, a fermented drink. Konbucha/Kobucha is made from Konbu seaweed. It is full of konbu glutamine and asparagine umami deliciousness. Konbucha is a salty seasoning so if you can’t find this, you can substitute with kosher salt instead. But Konbu gives nice umami… I hope you can find this seasoning. At Japanese supermarkets, you can find it in the tea section as we drink it as a tea.


Mentsuyu: If you use a store-bought mentsuyu, each brand is different concentrate.  Sometimes it's required to dilute 2 x water or 3 x water.  Follow the bottle's instruction.
