Udon are the thickest of the noodles served in Japanese cuisine. Udon are white, wheat-based noodles, that are 4-6mm in width. These noodles are served chilled with a dipping sauce in the summer months, or in hot dishes and soups when the temperature is cooler. Udon dishes include kitsune udon, Nabeyaki udon, curry udon, and yaki udon. However, sara udon is made using a different kind of noodle which is crispy.
