🕰️ History and origin

Soy sauce has deep roots in East Asia, with a history that goes back centuries. In simple terms, it’s a smart way to use fermentation to create a flavour-rich seasoning from soybeans and grains. You’ll find distinct regional styles across China, Japan and Southeast Asia, but light soy sauce is especially associated with Chinese-style everyday cooking, where it’s used constantly for stir-fries and marinades.
