Tauco, Taucu, Taotjo or Tauchu (Chinese: 豆醬; pinyin: dòujiàng; Pe̍h-ōe-jī: tāu-chiùⁿ) is a paste made from preserved fermented yellow soybeans in Chinese Indonesian and Malaysian cuisines. Tauco is made by boiling yellow soybeans, grinding them, mixing them with flour and fermenting them in order to make a soy paste. The soy paste is soaked in salt water and sun-dried for several weeks, furthering the fermentation process, until the color of the paste has turned yellow-reddish. Good tauco has a distinct aroma. The sauce is also commonly used in other Indonesian cuisines traditions, such as Sundanese cuisine and Javanese cuisine. Taucu is generally used in cooking by Chinese Malaysian, Singaporean and Bruneian.
