Sweet Red Bean Paste (Anko) – 餡子

If you are a fan of Japanese desserts then you are most likely a fan of red bean paste! Used in East Asian cuisines, red bean paste, or anko (餡子) has a sweet flavor similar to sweet potatoes and a chewy, almost creamy texture. Only two ingredients are needed to make red bean paste – sugar and adzuki beans. This is an easy recipe for tsubushian anko.

What Is Red Bean Paste?

Red bean paste, called anko (餡子) in Japanese,  is a sweet paste made of adzuki beans (red beans) and sugar that have cooked until the beans get mushy. It’s often used in Chinese, Korean and Japanese cooking, primarily in confections such as dango and dorayaki, and sometimes in soups (red bean soup called zenzai).

Types of Red Bean Paste

There are many different types of red bean paste available but the most popular ones in Japan are:

• Tsubuan (粒餡) – whole adzuki beans boiled with sugar and left as they are.
• Tsubushian (粒あん) – boiled adzuki beans that have been mashed with the skin on.
• Koshian (漉し餡) – boiled adzuki beans that have been passed through a sieve to remove the skin.
• Sarashian (晒し餡) – dried adzuki beans that have been reconstituted with water.
• Ogura-an (小倉餡) –  a mixture of koshian and tsubuan paste.

Ingredients for Red Bean Paste

• Adzuki beans (荅): We will be using about 100 grams for this recipe.
• Sugar: Plain granulated white sugar.
• Water: 4 cups to boil the sugar and adzuki beans.
• Salt: Just a pinch to balance the sweetness and nuttiness of the paste.

Are adzuki beans and kidney beans the same?

No. Azuki beans, also spelled azuki or aduki, are about half the size of kidney beans. They are higher in calories than kidney beans, but also contain more protein and fiber. Adzuki beans originate from China whereas kidney beans are native to Central America and Mexico.

What does anko taste like?

Like bean jam. Anko has a thick, mushy texture and can be used as a spread just like jam. The taste is quite sweet but not like your typical cookie or cake. It’s more complex because the nutty flavor of adzuki beans is so powerful it gives the paste an earthy taste on top of the sweetness.

How To Make Red Bean Paste

For this anko recipe, I’m using the tsubushian technique of boiling the beans and mashing them with the skin on. The texture isn’t as smooth as mashing them through a sieve but it’s just as delicious and pleasant to the palate.

1. Soak the beans. I recommend doing it overnight or for 6-8 hours.
2. Rinse and drain the adzuki beans. Then transfer them to a pot along with 4 cups of water.
3. Simmer the beans. It will take approximately 1 hour for the beans to get soft.
4. Add the sugar and salt. Keep stirring as you add the sugar and salt until a paste begins to form.
5. Place anko in a bow and let cool. Serve and enjoy!

How To Serve Red Bean Paste

There are several ways to serve red bean paste in Japan.

Red bean paste can be used:

• As a topping for green tea flavored shaved ice, anmitsu (jelly, fruit and ice cream dessert) and dango (rice dumplings).
• As a filling for mochi (rice cakes), dorayaki, manju (steamed cakes), and daifuku (strawberry wrapped in anko and mochi).
• In yokan (red bean jelly),  green tea popsicles and ice creams.
• As a spread for toast (ogura toast)
• In zenzai which is a traditional Japanese dessert soup.

Where to Buy Adzuki Beans

Finding adzuki beans is fairly easy. You can buy them at Whole Foods (in the bulk section) or at your local grocery store. Look for Bob’s Red Mill as they sell bags of them. And there is always Amazon if all else fails!

Storing adzuki beans

Store the beans the same way you would others – in an airtight container, away from sunlight, and in a cool, dry place like your pantry.

How Long Does Red Bean Paste Last?

For about 2-3 weeks in the fridge in an air tight storage container. You will be able to tell when it begins to spoil as the color will get darker and the smell becomes more prominent.

You can also freeze anko in an air tight storage container and it should keep for 2-3 months.
