Soy sauce
Soy sauce () is a popular food product used in Sri Lanka and is a major ingredient used in the nationally popular street food dish, Kottu. Soy sauce has largely been produced by the Sri Lankan Chinese community but its production has also spread to other communities in Sri Lanka. Soy sauce production in Sri Lanka is the same as the production of soy sauce in Indonesia. Fermentation occurs over a period of three months. The soy beans which are steeped in brine are then pressed to obtain a liquid sauce.
