Soy Sauce

A Brief History

Soy Sauce is known for its umami and salty, sometimes lightly sweet taste. This dark brown condiment has been used and made since the Western Han dynasty of Ancient China, Called ‘‘jiàngyóu’, it’s around 2,200 years old making it one of the oldest condiments of the world. Hundred of years later, Japan was then introduced to this versatile ingredient, spreading to the rest of Asia and came into contact with the US in the 1800’s, this has then been spread throughout Southeast and East Asia, and now everyone with a craving for something salty, savory and umami has it in their cupboard ready to be used.

Traditionally made from fermented soybeans, having a list of varying types ranging from light to dark, to different categories depending on which country you are. The process of making soy sauce evolved throughout the years from being used to preserve vegetables, meats, salt, and grains, to being one of the main seasonings to complete the recipe. It traditionally all starts with wheat fermented with salt, water and soybeans. Until most modern soy sauce just using soybeans, as the main component to create the base of the sauce. These require several months in production, starting from soybeans being fermented out in the open, under the sun. Boiling and mashing the soybeans sometimes with the addition of wheat, adding yeast cultures that provide the different taste or flavoring for the soy sauce. Brewed with a dry or wet salty brine that breaks it down for the 2nd fermentation, creating the depth of flavor we are all familiar with. It turns into a slurry, stained to separate the liquids from the solids, pasteurized to avoid molding, then finally bottled to be aged then sold.

While Soy Sauce might not be the first ingredient you think about when creating a dish. But it’s such an important ingredient that just completes the dish and helps bind all the flavors together. It’s used and needed so much that there have been alternative vegan, wheat-free, and gluten-free options.
