Learn how to make anko sweet red bean paste from scatch. Step-by-step pictures included.
Anko (あんこ, 餡), or sweet red bean paste, is used in many confectioneries in Japan. It is usually prepared by boiling azuki beans, sometimes mashing them, and then sweetening the paste with sugar. The most common types of read bean paste include Tsubuan and Koshian.
Other varieties of red bean paste includes Shiroan (白あん), made from Japanese white beans, and Kurian (栗あん) made from chestnuts.
Tsubu-an (Chunky Red Bean Paste)
Tsubuan (粒あん) is prepared by boiling and sweetening with sugar, but otherwise untreated. Hence the texture is chunky. My recipe below shows you how to make chunky read bean paste from scratch.
Koshi-an (Smooth Red Bean Paste)
Koshian (こしあん) is prepared by passing through a sieve to remove bean skins. The texture is smoother and is most commonly used for wagashi (traditional Japanese confectionery).

- 200 g Azuki beans (200 g = 7 oz or a little bit less than 1 cup which is 220g) (I used Hokkaido Dainagon Azuki Beans : bigger than regular azuki)
- 200 g sugar (200 g = 7 oz or 1 cup)
- Pinch salt (kosher or sea salt; use half if using table salt)
Gather all the ingredients.
- Soak the azuki beans overnight (8-12 hours).
- Rinse azuki beans.
- Use a big saucepan/pot because the amount of azuki beans will double after cooking. Put washed azuki beans in the pot and pour water till 1-2 inch above azuki beans. Turn the heat on high.
- When boiling, turn off the heat and cover with lid. Let it stand for 5 minutes.
- Throw away water and put the azuki beans into a sieve.
- Put the azuki beans back in the pot. Add enough water just to cover the beans and turn the heat on high. Once boiling, turn down the heat to medium low and keep it simmering.
- Once in a while push the azuki beans under the water with slotted spoon. Water will evaporate so you need to keep adding water to cover just above the beans. If you put too much water, the beans will move and break. If you need to leave the kitchen, make sure to turn off the heat. You will be cooking for 1+ hour.
- Pick one azuki bean and squeeze it with your fingers. If it is smushed easily, it’s done.
- Turn up the heat to high and add sugar in 3 separate times. Stir constantly. When you draw a line on the bottom of the saucepan and see the surface for more than 2 seconds, add salt and turn off heat. Anko will thicken more when it cools.
- Pour into a container to cool down. Do not leave it in the pot. Cover with plastic wrap and keep in the fridge to store after cool down. If you aren't planning to use it all at once, you can divide it into 100g packages. Wrap in plastic bag and store in Ziploc Freezer bags and can store in fridge for a week and freezer up to a month.
