Udon vs Ramen: What Is Ramen?

It is believed that ramen noodles were introduced to Tokugawa Mitsukuni by a prominent Daimyo of Mito, a scholar from the Ming Dynasty. Hence, ramen is said to be adapted from the Chinese immigrants.

Ramen is a Japanese noodle soup made of flavored broth, noodles, meat or vegetables, and topped with boiled eggs. Ramen dishes are among the delicious and famous fast foods in Japan that are often sold by street vendors and small restaurants in the country.

Just like udon, ramen also comes in different shapes and sizes. The noodles can be thick or thin, long or short, and straight or curly. 

All varieties of ramen noodles are made with kansui. This alkaline solution gives a golden chewy texture to the noodles, and creates umami flavors.

Ramen noodles have different varieties and styles.

Different Varieties Of Ramen: Broth Styles

Ramen comes in different varieties and toppings. Below are the major and popular types of ramen noodles not only in Japan, but in all ramen restaurants all over the world.
