HAKUBAKU Organic Soba Noodles are thin, brownish-gray Japanese noodles made from a mix of wheat and buckwheat flour. They’re about as thick as spaghetti and can be used in lots of dishes. You can enjoy them hot in soup, cold with dipping sauce, or even in stir-fries and salads. In Japan, soba is everywhere—from quick street food to fancy restaurant fare, and even homemade. Plus, buckwheat, one of the main ingredients, is known for its health benefits.
