The term "wafu" means "Japanese style" in Japanese, and this sauce typically combines soy sauce, mirin, and sometimes vinegar or sesame oil. Shimeji mushrooms, which are often featured in the sauce, are prized for their unique texture and nutty flavor, making the combination both savory and aromatic. Interestingly, wafu sauces are versatile—they’re used not only in mushroom dishes but also for grilled meats, vegetables, or even as a salad dressing!
