🌸 What Is Japanese Sweet Red Bean Paste (Anko)?
Anko (餅子) is a sweet paste made primarily from adzuki beans (red beans) and sugar. It is a cornerstone in Asian red bean recipes, especially in Japanese, Chinese, and Korean cuisines. In Japan, it comes in several varieties depending on the texture and preparation method:
- Tsubuan (粒あん) – Chunky red bean paste with whole or partially mashed beans.
- Koshian (こしあん) – Smooth red bean paste that’s been sieved to remove skins for a creamy texture.
- Shiroan (白あん) – Made from white kidney beans, for a lighter color and taste.
This sweet bean paste is used as a filling, topping, or base for countless dishes, adding richness and sweetness without overpowering other flavors.
🍬 Why Is Anko So Popular in Japanese Sweets?
Red bean paste is not overly sugary—it has a gentle, natural sweetness that pairs perfectly with both traditional and modern desserts. It’s used in:
- Dorayaki (pancake sandwich with anko filling)
- Taiyaki (fish-shaped pastries)
- Yokan (a jelly-like bean dessert)
- Anman (steamed buns filled with red bean paste)
- Daifuku and Mochi (glutinous rice cakes)
- Even in some ice cream and drinks!
Anko’s versatility lies in its mild flavor and thick, spreadable consistency. It complements glutinous rice, doughs, jellies, and even dairy products.
Because of its subtle sweetness and rich history, anko remains a treasured part of Japanese cuisine and is enjoyed all year round, especially during festivals and tea ceremonies.
🍽 Ingredients You’ll Need
To make about 2 cups of Japanese sweet red bean paste, gather the following:
- 1 cup dried adzuki beans (found in Asian markets or online)
- 4 cups water (for boiling)
- ¾ to 1 cup sugar (adjust to taste)
- Pinch of salt
Optional: Some recipes include a tablespoon of honey or mirin for added depth.
👩🍳 How To Make Anko (Japanese Sweet Red Bean Paste)
Let’s dive into a step-by-step guide for making homemade anko paste:
Step 1: Rinse and Soak the Beans
Rinse 1 cup of dried adzuki beans under cold water until the water runs clear. This removes excess starch and impurities. Soaking overnight softens the beans and reduces cooking time.
Step 2: Parboil to Remove Bitterness
Place the beans in a pot with enough water to cover them. Bring to a boil and simmer for 5 minutes. Drain and discard the water. This step helps remove any bitter compounds naturally present in adzuki beans.
Step 3: Cook the Beans
Refill the pot with 3-4 cups of fresh water. Simmer the beans on low heat for 45 minutes to 1 hour, until they are tender and easily mashed with your fingers. Add water as needed during cooking to keep the beans submerged.
Step 4: Drain and Sweeten
Once cooked, drain the beans but reserve a small amount of the cooking liquid. Return the beans to the pot, add ¾ cup of sugar (or more depending on your preference), and a pinch of salt. Stir gently and cook over low heat until the sugar dissolves and the mixture thickens.
If it gets too thick, add some reserved cooking liquid to reach your desired consistency.
Step 5: Choose Your Texture
- For tsubuan (chunky): Mash the beans slightly and stop here. You’re done!
- For koshian (smooth): Press the mixture through a fine mesh strainer or cheesecloth, then cook the strained paste again to reduce excess moisture.
❄️ Storage Tips
- Refrigerator: Store in an airtight container for up to 5 days.
- Freezer: Freeze in small batches for up to 2 months. Simply thaw in the fridge before using.
Freezing anko is especially convenient if you like to make traditional desserts regularly.

📋 Nutritional Benefits of Sweet Beans

- Protein
- Iron
- Antioxidants
When paired with minimal sugar, bean paste recipes can offer a guilt-free way to enjoy dessert with added nutrition.
💡 Tips for Perfect Red Bean Paste Every Time
- Don’t overcook: Too much cooking will make the paste overly dry or gummy.
- Control the sweetness: Taste as you go. Some like it sweeter, others prefer the bean’s natural flavor.
