Sweet azuki bean paste is used in various Japanese sweets. This is a type of anko called tsubu-an. Tsubu-an contains skins of azuki beans.


  • 1/2 pound or 1 1/3 cup azuki beans
  • 2 cup Japanese Johakuto (white sugar), or 1 1/4 cup granulated sugar (adjust the sweetness to your preference)
  • 1 teaspoon salt (adjust the amount of salt to your preference)

Steps to Make It

  5. Drain in a colander.

  6. Put the azuki beans back in the pot and add about four cups of water.

  7. Bring to a boil on high heat.

  8. Turn down the heat to low and simmer azuki beans for about one hour or until softened.

  9. Carefully drain the liquid from the pot.

  10. Add sugar and salt to your taste and stir azuki.
