  • Pot
  • Blender



  • 1 cup Glutinous Rice Flour + more for dusting
  • 1/2 cup Warm Water
  • 200 g Red Bean Paste roll into small balls

Red Bean Soup

  • 120 g Red Beans
  • 4 cups Water
  • 1/4 cup Sugar


Red Bean Soup:

  • Rinse the beans to clean off the impurities.
  • Boil the red bean with water for 1 hour or until beans are soften and mushy.
  • Add in the sugar and stir well.
  • Put in a blender to puree the soup for a smoother consistency.


  • Put the sweet rice flour into a mixing bowl. Slowly add in the warm water, while stirring to form a dough. The dough can’t be too wet, or it will not hold its shape. Cover with a damp towel.
  • Roll the red bean or mung bean paste into tiny round balls and set aside for wrapping.
  • Now boil some water in a small pot, take out a small piece of the dough, about 1” in diameter, wrap the fillings and seal it, and roll into round balls.
  • While you are assembling, bring a medium pot of water to a boil. Add the balls and stir immediately to prevent them from sticking.
  • Remove from the pot once the balls started to float to the surface. Add the balls in a bowl of cold water and set aside. Add in the balls into the red bean soup only when you are about to serve.


  • Use Azuki red bean for cooking the red bean soup 
  • You can also buy store bought mochi for to save time
