Soy sauce isn’t just a staple in Asian kitchens — it’s a 2,500-year-old treasure that once held the same value as silver. Used for preserving food and enriching flavor, this umami-packed liquid was so essential that ancient Chinese families once used it to pay taxes or barter for goods. From currency to condiment, soy sauce has a flavorful story to tell.
Soy sauce wasn’t just a condiment — it was once so precious, it served as a form of currency in ancient China.
Long before modern seasoning or refrigeration, soy sauce played a vital role in everyday life. Dating back over 2,500 years to the Zhou Dynasty, the earliest versions of soy sauce were known as “jiang” (醬) — a fermented mixture made from soybeans, grains, and salt. It wasn’t the dark liquid we recognize today, but it was still deeply flavorful and rich in umami, the fifth taste.
As the technique of fermentation evolved, soy sauce became a household staple, prized for its ability to preserve food and enhance flavor. In times of scarcity — particularly during wars or droughts — soy sauce’s long shelf life and essential use made it as valuable as silver. There are records suggesting that families would trade soy sauce or offer it in place of money to pay taxes or barter for goods.
A Global Journey
From its roots in China, soy sauce traveled across East Asia, eventually taking on unique forms:
Japan developed “shoyu” with a smoother, sweeter profile.
Korea made “ganjang,” often used in traditional soups.
Indonesia created “kecap manis,” a sweetened, molasses-like version.
Today, soy sauce is a culinary bridge that connects cultures, whether you’re enjoying sushi, dumplings, stir-fry, or even fusion dishes.
