sourdough n.also sour-dough, early 14c., "leavened bread," also "leaven" (late 14c.), from sour (adj.) + dough. Compare German Sauerteig, Dutch zuurdeeg, Danish surdeig. The meaning "fermented dough" left from a previous mixing is by 1868. This was extended during the 1898 Yukon gold rush to "Arctic prospector or pioneer," from their practice of saving a lump of fermented dough as leaven for raising bread during the winter. updated on March 24, 2023 |
