Adzuki beans {Chi Dou 赤豆} fun facts

We call a variety of beans “red beans” because of their bright red color. Adzuki beans are the classic ones, also known as Chi Dou {赤小豆} in Chinese. “Chi” means “red”, “Dou” literally translates as beans.

Adzuki beans come in various sizes, either the size of black beans or mung beans. By the way, smaller adzuki beans are more common in China, called Chi Xiao Dou {赤小豆} in Chinese, or red little beans.

Adzuki beans are incredibly healthy & nutritious, doing a wonderful job nourishing and detoxing our bodies at the same time. For instance, they are rich in fiber, protein, and manganese. Adzuki beans are attributed to many health benefits such as improved digestion, lower risk of type 2 diabetes, and heart disease. Traditional Chinese Medicine {TCM} is a huge fan of them.

Adzuki beans have a pleasant warming, mild nutty taste. This, along with the fact that they have a bright red appealing color and contain superfood nutrients, makes them one of the popular ingredients for Chinese Eight Treasure Porridge.

How to cook adzuki beans?

Rinse the dried adzuki beans well and soak in more than twice the amount of water overnight to let them fully hydrate. They double their sizes after good hydration.

People either boil & simmer or steam to cook the hydrated adzuki beans. I usually use the former for easier cooking and more energy-efficient cooking.

Use either a cast-iron stockpot, a quality stockpot such as Tri-ply stainless pot that retains heat well. Add water and the hydrated adzuki beans, bring them to a boil, and then simmer for about 1 hour and 40 minutes.

You can surely use a slow cooker. If you do, I recommend you bring it to a boil via stovetop cooking prior to pouring it into the slow cooker and then simmer.

How much water should I use for boiling & simmering adzuki beans?

To preserve the taste & flavor of the adzuki beans, use a minimum amount of water when using the boiling & simmering method.

This is one of the key reasons people prefer the steaming method, as adzuki beans’ flavor won’t get watered down during the steaming process. However, if I use just the right amount of water, I shall be able to accomplish this using boiling & simmering method.

After soaking & hydrating the adzuki beans, add the hydrated beans into the cast-iron stockpot, along with 2 cups of water.

How to make Red Bean Paste?

Homemade Red Bean Paste Optional Step 1 – Puree the cooked adzuki beans

If you prefer a super smooth red bean paste, then do this optional step to puree the cooked adzuki beans. Use a coarse stainless steel strainer to remove the skins of the beans.

By the way, this colander is a very handy tool, I use it to easily make homemade pureed tomatoes for delicious food like Luo Song Tang {罗宋汤 Shanghai-style Borscht Soup}, Red or Sweet and Sour Pork {Gu Lao Rou 古老肉}。

I usually skip this step as I enjoy the nutrients from the whole beans, am completely fine with the taste & texture it is, and definitely prefer the easier way LOL.

Homemade Red Bean Paste Step 2 – Turn mashed adzuki beans into a sweet paste

Add cooked adzuki beans to a hard-anodized fry pan, and use a potato masher to mash the cooked beans. If you have pureed the cooked beans, then just add them to the frying pan.

Turn the heat to medium, and add coconut oil, cane sugar, and turbinado sugar to the pan. Fold the coconut oil and sugar into the adzuki beans and till it starts to bubble. Then continue to fold and mix for another 15 minutes or so, or till the whole thing turns into a smooth paste.

Notes

  • This recipe makes about 5 cups of red bean paste.
  • Save the juice left in the cast iron pot after cooking the beans, if any are left, they make great red bean tea.
  • Organic virgin coconut oil, a superfood, has a unique aroma and taste and many people are big fans, me included. If you are not, you can use avocado oil instead. Avocado oil is also a superfood oil with an extremely neutral almost tasteless flavor, which makes it versatile for all kinds of cooking and baking.
  • You can either use a food & meat grinder with the finest setting or a potato masher to turn the cooked adzuki bean into a mash.
  • If you prefer a super smooth red bean paste, you shall use a fine setting when grinding/mashing. After that, use a fine stainless strainer to puree.
  • Coconut oil is in a solid state unless the surrounding temperature is well above 70 degrees Fahrenheit. I, therefore, use a kitchen scale to measure coconut oil in grams for easier and more practical measurement.
