Soba-yu is the water left after boiling soba noodles. It is said that drinking buckwheat is good for your health because the nutrients in it are leached out.
The custom of Sobayu began in Shinshu, spread to Edo, and became known throughout the country. In the Kanto region, sobayu is often served when eating soba, but in the Kansai region, udon is more popular than soba, so there are few restaurants that serve sobayu.
The taste of soba soup varies depending on the shop, but it is mostly flavorless and is meant to be enjoyed by the flavor and aroma of the soba. There are several ways to drink soba hot water: by drinking it as is, by diluting it with soba soup, or by adding seasonings.
If you want to make soba soup at home, just mix buckwheat flour and hot water and bring to a boil. For more information, please refer to the article below.
