  • Begin by preparing azuki beans. If using dry, bring 1 cup of beans (rinsed) to a boil with 3 cups water. Once boiling, lower heat to a simmer.
  • Allow beans to cook for about 1-2 hours, or until tender. Taste to test whether it's ready.
  • Once ready, make sure there is excess liquid among the beans. If not, add water. Do not drain!
  • Add your sugar and on low heat, stir until completely incorporated and melted down. Adjust to your taste.
  • Serve by spooning red beans and some of the "soup" into a small bowl. Add prepared mochi and enjoy.


Serving Tips

  • You can serve hot zenzai right off the stove or serve it cold. Both are delicious ways to enjoy this sweet treat. 

Storage Tips

  • To store, let the leftovers cool completely. Then, store in an airtight container in the fridge for up to 2-3 days. Serve hot or cold, and enjoy!
