Soba noodles are thin, brown to grey, Japanese noodles made of wheat and buckwheat flour. They are roughly as thick as Italian spaghetti, and are used in various hot and cold dishes.
Soba can be served with various toppings, hot in a soup broth or chilled, and served with a dipping sauce, scallions and wasabi. Soba can also be used in stir fries and salads.
In Japan, soba noodles are found everywhere. They can be a popular, inexpensive fast food, an expensive exclusive specialty restaurant item, or made at home.
