Shoyu (醤油), or Japanese soy sauce, is a fundamental condiment in Japanese cuisine, brewed from fermented soybeans, wheat, salt, and water. This particular Honjozo-style shoyu from Wadakan is traditionally brewed using 'Fukuryu Sui', the renowned soft, clear underflow water from the Hakkoda mountains in Aomori, Japan. This gives it a remarkably clean, well-rounded, and mellow umami flavour compared to mass-produced soy sauces. Its balanced profile makes it an excellent all-purpose seasoning for everyday cooking, from stir-fries and marinades to being used as a dipping sauce for sushi, sashimi, or gyoza dumplings. For a simple yet flavourful dressing, mix this shoyu with a little rice vinegar and sesame oil. This authentic Japanese pantry staple is ideal for anyone looking to add genuine depth and flavour to their home-cooked Asian dishes.
