Momen Tofu (木綿豆腐)

    Firm Tofu (or Momen Tofu)

    Japanese people loves tofu so much that it appears in various Japanese traditional dishes. In addition, there are so many different kinds of tofu even at the supermarket. Therefore, if you are now in Japan or are interested in Japanese food, it is recommended to differentiate between these types to find the one you need. Today, in this article, we would like to introduce about Momen Tofu (木綿豆腐)! Let’s go and find out!

    What is Momen Tofu?

    Tofu is made by adding bittern (the leftover thing that is formed when you extract salt from seawater) to soymilk. Like soybeans, it contains a lot of protein, but easy to digest and absorb. 

    In Japanese, momen (木綿) literally means “cotton” and momen tofu refers to firm or hard tofu. It has rough texture and a rich flavor. Other than momen tofu, there is another common type of tofu named “kinu” or “kinugoshi” (きぬ/絹ごし), which literally means silk. Just like its name, this type of tofu is soft tofu which has a silky and smooth texture.

    Because of its firm texture, unlike silken tofu, momen tofu is recommended for stew, stir-fry while Kinu Tofu can be used in Hiyayakko, salads, etc.

    History of Firm Tofu

    Origin of tofu

    The origin of tofu is actually not clear. There are various theories on the birth of this dish.

    Originated in the Han Dynasty

    According to one theory, it was founded 2,000 years ago by King Huainan and Liu An of the Han dynasty in China. However, since there is no record of tofu until the Tang Dynasty (618-907), most of people do not believe in this theory.

    Originated in the Tang Dynasty

    The most influential theory is that tofu first appeared in the middle of the Tang dynasty from 8th to 9th century. In the 6th-century, a Chinese book named “Seimin Yojutsu” (Qi Min Yao Shu) contained a description of soy sauce, but not tofu. Therefore, tofu was not yet available in those days.

    The word “tofu” is said to have first appeared in “Sei-iroku” (清異録) written 1000 years ago. As the result, most of people believe that the origin of tofu was in the middle of the Tang Dynasty (8th-9th century).

    Introduction to Japan

    After its invention in China, tofu was then introduced to Japan during the Nara and Heian periods. It seems that during the “Kentoshi” (遣唐使時代), Buddhist monks brought the knowledge of “tofu” to Japan and popularized it along with Buddhism. 

    At that time, it was the food for special classes such as monks and aristocrats. After that, in the Edo period, tofu finally appeared in the table of the common. However, during this time, it is believed that people only ate firm tofu (or momen tofu). Thanks to this boom, so many tofu dishes were born. Kinu tofu was then invented in the middle of the Edo period. Tofu was so popular in the Edo period as there were not only stores but also street vendors selling its.

    In 1782, “Tofu Hyakuchin” (豆腐百珍), a book which introduces 100 differents tofu dishes, became a best-seller.

    “Kentoshi” (遣唐使時代) is Japanese missions to Tang China during the Tang Dynasty and Nara periods. Kentoshi-sen (遣唐使) were also the name of the ships that carried the Imperial Japanese Envoys to China. These envoys places an important role as the cross-cultural exchanges between Japan and China. The mission is to acquire as much academic and technological knowledge from the advanced nation China. As a matter of fact, food such as miso, igyoza or tofu were also included.

    Firm Tofu FAQ

    When to use Firm Tofu and Silken Tofu?

    As you know, there are two common types of tofu in Japan: momen (firm) tofu and kinu (silken) tofu.

    Firm tofu has a good flavor and is hard to crumble so it is suitable for stew, stir-fry and tofu hamburger. Otherwise, the soft and smooth texture of kinu tofu is suitable for hiyayakko, salads or soup, etc.

    What is Atsuage and Kinu-atsuage?

    Atsuage (厚揚げ) is generally deep-fried momen tofu (or firm tofu) that has been drained of water and is characterized by its rich flavor. On the other hand, kinu-atsugae (絹厚揚げ) is deep-fried tofu made from silken tofu (kinu tofu) with a smooth texture. 

    Other than Atsuage, if you like fried tofu, we also recommend Abura-age (油揚げ). Let’s find out here!
