Soba refers to a type of Japanese noodle primarily composed of buckwheat flour, which may be mixed with varying amounts of wheat flour. These noodles are characterized by their distinct ashen brown color and a slightly grainy texture.
In culinary practice, soba is versatile and can be served in several ways. It is commonly enjoyed either chilled with a dipping sauce or served hot in a noodle soup. The noodles serve as a base for a wide variety of different dishes.
