A sweet reddish-brown paste that’s either smooth or chunky, red bean paste, or anko/an, is an essential player in traditional Japanese and modern desserts like ice cream and pastries.
Anko (餡子,あんこ), or (餡, あん), is a sweet red bean paste made from azuki beans. It’s one of the essential ingredients for wagashi. It’s also loaded with nutrients, such as fiber, folate, protein, vitamins, and minerals.

What Is Anko (Red Bean Paste)
Anko, or red bean paste, is used in Japanese, Chinese, and Korean desserts. It’s made by boiling azuki beans/adzuki beans with sugar and a pinch of salt. The Japanese use the sweetened paste in many traditional Japanese sweets, such as Daifuku Mochi, Dango, Dorayaki, Taiyaki, Manju, Zenzai, and Anpan. You could also top your morning toast or pancakes with the paste for a fusion dessert.
What Does It Taste
It has a creamy texture and flavor like sweet potatoes. The beans are not naturally sweet and are sweetened with brown or white sugar during the cooking process.
Types of Red Bean Paste
There are different types of red bean paste in a spectrum of consistencies. Like chunky vs. creamy peanut butter, it’s a personal preference.
Chunky Red Bean Paste – Tsubu-an (つぶ餡, つぶあん)
Tsubu-an (つぶあん) is a chunky paste. It’s made by cooking the beans until soft but leaving whole beans intact without pureeing until smooth.
Because the beans are still chunky, this red bean paste is an excellent filling for sweets like Strawberry Daifuku, Dorayaki, Daifuku, and Taiyaki.
Fine Red Bean Paste – Koshi-an (こし餡, こしあん)
Koshi-An (こしあん) is very smooth, pureed azuki beans. The beans are cooked until soft and passed through a sieve for a smooth texture without the bean skins.
Tsubushi-An (つぶし餡)
The texture is between Tsubu-an and Koshi-an where some of the beans are mashed with the skins.
Ogura-An (小倉あん)
Traditionally, Ogura-an (小倉あん) was made with Koshi-an mixed with Tsubuan and cooked in sweet syrup. It’s made with Dainagon Azuki Beans (大納言小豆), the highest quality of azuki beans.
