Cooking Tips:

  • You can also bake mochi in a toaster or frying pan if you like the mochi to be crispy. Another option is boiling the mochi, which makes it softer and easier to mix into the oshiruko soup.
  • A hint of soy sauce makes this sweet soup taste better because you get that sweet-salty umami thing going!
  • This recipe used chunky red bean paste, but you can use smooth red bean paste as well if you prefer. Or, you can even make your own red bean paste.
