Have you ever knocked back a nice tall glass of soy sauce? Me neither. Most are unbearably salty and harsh, useful only for cooking. But not all soy sauces are created equal.
This shoyu—the Japanese word for “soy sauce”—comes from Suehiro, a firm that’s been making soy sauce since 1879 in Tatsuno, Japan, about 90 minutes west of Osaka. They start with soy beans and wheat grown in Japan, plus water and sea salt. Once the first batch of soy sauce is fully prepared, to make a “double brewed” shoyu, they start as if to make a new, second batch with more wheat and soy beans, but this time they replace the water and salt with the first batch of soy sauce.
The result is a soy sauce that’s smoother and softer. It’s still plenty salty, but with the harsh edges rounded off. It’s equally great blended into sauces or used for dipping or sprinkling at the end of cooking.
