Udon is a type of thick, chewy Japanese noodle made from wheat flour, water, and salt. Typically white in color, udon has a smooth, springy texture that makes it ideal for absorbing the flavors of broths, sauces, or stir-fries. These noodles are commonly served in a variety of dishes—from hot soups like kake udon (simple broth with scallions) to chilled versions like zaru udon, enjoyed with a dipping sauce. Udon's mild flavor makes it a versatile base for both traditional and modern recipes.
