This ponzu that Suehiro makes is top notch! They use a blend of four different Japanese citrus: Yuzu for aroma, Sudachi for acidity, Daidai for sweetness & Yukou for mildness. The floral/citrus fragrance of this ponzu is out of this world. It does not stop there as the beautiful flavor of the citrus is balanced by the soy sauce & mirin. This is further elevated by the umami from the Ma Konbu dashi that Suehiro adds to this product. Use this with raw fish, veggies, mayonnaise, noodles, etc. Please refrigerate after opening. About the producer: Located in Tatsuno City, Suehiro Shoyu has been using traditional methods to brew usukuchi (light colored) soy sauce since 1879.
