Korean Seasoned Bellflower Root
In the five-color namul set for Chuseok and Seollal ancestral tables, bellflower root is the white one. The torn root is rubbed hard with salt to draw out its bitterness and rinsed until the cloudy water runs clear, then dressed with gochujang, vinegar, and sugar. Since it is never cooked, it stays crunchy long enough to be made ahead.
