Soy sauce (also called soya sauce) is a condiment made from a fermented paste of boiled soybeans, roasted grain, brine, and Aspergillus oryzae or Aspergillus sojae molds. Soy sauce in its current form seems to have begun in the 2nd century AD in China and spread throughout East and Southeast Asia where it is used in cooking and as a condiment.
Soy sauce originated in China sometime between the 3rd and 5th century from a meat-based fermented sauce named jiang (). Its use later spread to East and Southeast Asia. Like many salty condiments, soy sauce was originally a way to stretch salt, historically an expensive commodity. In ancient China, fermented fish with salt was used as a condiment in which soybeans were included during the fermentation process. Eventually, this was replaced and the recipe for soy sauce, (), using soybeans as the principal ingredient, with fermented fish-based sauces developing separately into fish sauce.
Records of the Dutch East India Company list soy sauce as a commodity in 1737, when seventy-five large barrels were shipped from Dejima, Japan, to Batavia (present-day Jakarta) on the island of Java. Thirty-five barrels from that shipment were then shipped to the Netherlands. In the 18th century, diplomat and scholar Isaac Titsingh published accounts of brewing soy sauce. Although earlier descriptions of soy sauce had been disseminated in the West, his was among the earliest to focus specifically on the brewing of the Japanese version. By the mid-19th century, Japanese soy sauce gradually disappeared from the European market, and the condiment became synonymous with the Chinese product. Europeans were unable to make soy sauce because they did not understand the function of Aspergillus oryzae, the fungus used in its brewing. Soy sauce made from ingredients such as Portobello mushrooms were disseminated in European cookbooks during the late 18th century. A Swedish recipe for "Soija" was published in the 1770 edition of Cajsa Warg's Hjelpreda i Hushållningen för Unga Fruentimber and was flavored with allspice and mace.
