Udon Overview

What is Udon?

Udon is a Japanese or Japanese dish cooked with thick noodles made of long, kneaded slices of wheat flour.
In Japanese it is generally written in hiragana as "うどん" but is sometimes written in kanji as "饂飩" as well.

Udon has been eaten all over Japan since ancient times as a simple, easy-to-prepare meal for the common people, as a substitute for rice, and as a food for "Hare" (ハレ, celebratory occasions).
The recipes and ingredients used vary from region to region.

Noodles thinner than udon are generally divided into "hiyamugi" (冷麦, thin udon noodles served chilled) and "somen" (素麵) but there are no strict rules for kanmen (乾麺, dried noodles) except for the thickness of the noodles.
There is also inaniwa udon which is made with thin noodles, and kishimen and himokawa which are thin noodles, are also included in the kanmen category.

The History of Udon

There are many theories about the origin of udon.
・One theory suggests that the origin of Udon is derived from wontons brought over from China during the Japanese missions to Tang China in the Nara period.
・Another theory is that wonton, written "餛飩" and pronounced "konton" in Japanese was accidentally written as "饂飩," pronounced "unton," and eventually became "udon."
・Further, there is a theory that Udon was introduced to Shikoku by Kukai, who was a part of the envoys to Tang China during the Heian period, and Sanuki Udon was born.
In any case, while there are many other theories about the origin of udon, what is known today is that it was widely eaten during the early Edo period.

There are two methods of making udon: Te-uchi (手打ち) and Te-nobe (手延べ). Te-uchi noodles are generally cut with a knife so they are square, whereas Te-nobe noodles are round. In the past, hand-made was the most common way to make udon, but nowadays, the mainstream method of making udon is to use a noodle-making machine or to carry out the entire process by machine.

The name of the dish changes depending on the dish with which the udon is served. If served in a bowl it is called "kake udon," if served on a zaru it is called "zaru udon," and if served in a pot (鍋, nabe) it is called "nabe-yaki udon.

The Top 3 Udon of Japan

Nowadays, there are three major styles of Udon in Japan. While there are no specific organizations, such as the Japanese Udon Association, that recognize the three major types of udon, each region has certain udon that they refer to as such.

・Sanuki Udon "讃岐うどん" (Kagawa Prefecture)
Udon is a specialty of Kagawa Prefecture, so much so, that it is also known as the "Udon Prefecture."

Inaniwa udon refers to dried udon noodles made with a te-nobe method in southern Akita Prefecture.
It is thicker than hiyamugi and has a slightly yellowish color.

Himi udon is generally made with a te-nobe style and is characterized by the softness of te-nobe noodles but the strength found in te-uchi noodles, which is achieved by kneading it with great force.

・Kishimen "きしめん" (Aichi Prefecture)
Kishimen is an umbrella term for thin Japanese noodles and the dishes that usem.
Kishimen is flatter than normal udon and the noodles are longer than udon, so it takes less time to cook.
