noun which may take the genitive case particle 'no', noun
with extra broth; soupy; extra sauce
Used mainly for gyudon (beef bowl) and similar dishes to request more broth or sauce than usual. Often used as a noun or no-adjective in ordering contexts.

つゆ抜き means 'without broth', the opposite of つゆだく. Both are common ordering terms at gyudon restaurants.
Compound of つゆ (broth, sauce) and だく, a colloquial suffix meaning 'lots of' or 'with extra'. The exact origin of だく is uncertain, but it is used in similar food-related terms like 脂だく (with extra fat).
