Soba

Soba is noodles made mostly from buckwheat. 

Buckwheat is not a type of wheat, it is not in the same group of plants. The plant buckwheat is a scraggly shrub and its seeds are somewhat triangular. The seeds do not have gluten but the noodles are made with regular wheat flour also for its adhesive qualities, usually 80% ground buckwheat seeds, and 20% wheat flour. 

The base is chicken stock, the commercial flavorings are soy sauce, sesame oil, and white vermouth this time instead of sake. 

The noodles are boiled for about 90 seconds, a little longer at altitude, until they soften. They are rinsed in cold water to rid surface starch, careful not to over handle, they are delicate more so than regular pasta, then doused in ice water to completely halt cooking action. The noodle-water reserved to include in a sauce or a broth, the same way as with Italian pasta.
