Seiro soba (buckwheat noodles)（Seiro Soba (Soba Noodles)
The “seiro” in seiro soba refers to a steamer basket, a tool used to steam steamed buns, yakisoba, etc. The word “seiro” originated in the Edo period (1603-1868). The term originated in the Edo period. At that time, the most common type of buckwheat was jyuwari-soba, which was made from buckwheat flour alone, rather than nihachi-soba, which used wheat flour as a binder. However, the buckwheat flour used to make the buckwheat tends to tear easily when it is boiled. Therefore, the buckwheat noodles were steamed in a steamer basket and served. Even today, when boiled soba is the mainstream, it is still called “Seiro-soba” (buckwheat noodle). Zarusoba and morisoba are also often served in a steamer basket.
