What is Seoul Cabbage (Put Baechu) ?

"Put" means "unripe." Other than Putbaechu, "put" is used as a prefix for green pepper (put gochu) and green apples (put sagwa).

Therefore, putbaechu means "young cabbage". The leaves are thinner than a napa cabbage and the leaves are more leafy green than napa cabbage, and more tender.

Seoul Green Cabbage (Eolgari Baechu 얼갈이 배추, Put Baechu 풋배추) are a Korean loose-head type cabbage with narrow light green leaves.
