Sauerkraut
Sauerkraut (/ˈsaʊ.ərˌkraʊt/; German: [ˈzaʊ.ɐˌkʁaʊt], lit. 'sour cabbage') is finely cut raw cabbage that has been fermented by various lactic acid bacteria. It has a long shelf life and a distinctive sour flavor, both of which result from the lactic acid formed when the bacteria ferment the sugars in the cabbage leaves.
