Soya sauce is a condiment made from a fermented paste of boiled soybeans, roasted grain, brine, and Aspergillus oryzae or Aspergillus sojae molds. After fermentation, the paste is pressed, producing a liquid, which is the soya sauce, and a solid byproduct, which is often used as animal feed. Soya sauce is a traditional ingredient in East and Southeast Asian cuisines, where it is used in cooking and as a condiment.
