What is the difference between ramen, udon, and soba noodles?

Ramen, udon, and soba are all popular types of Japanese noodles, but they have distinct differences. Ramen noodles are made from wheat flour, salt, water, and kansui, which gives them their characteristic springy texture and yellow color. Udon noodles are also made from wheat flour, but they are much thicker and chewier than ramen noodles. Soba noodles are made from buckwheat flour, which gives them a nutty flavor and a slightly rougher texture. Soba noodles are often served cold with a dipping sauce, while ramen and udon are typically served in a hot broth.
