Soba noodle dipping sauce

Soba noodle dipping sauce, known as 'tsuyu', is a savory and umami-rich Japanese condiment used for cold or hot soba noodles. It is typically made from a base of dashi (stock from bonito flakes and kelp), soy sauce, and mirin, often with added kombu and dried shiitake for depth. This sauce is a staple in Japanese cuisine, particularly in regions like Nagano, where buckwheat farming is prominent.
