This crunchy, chewy white root is a staple Korean vegetable that you might see as a side dish (banchan) or in your bowl of mixed rice (bibimbap). You can also make a spicy version of this with Korean chili pepper powder (kochugaru), but this is the simpler way to prepare this - with a lighter touch.


  • 8 ounces dried bellflower roots, or balloon flower roots

  • 2 tablespoons vegetable oil

  • 2 teaspoons minced garlic

  • 1 teaspoon sesame oil

  • 2 tablespoons sea salt

  • Sesame salt, to taste

Steps to Make It

  1. Soak dried doraji/bellflower roots overnight in warm water to reconstitute.

  2. Using a small sharp knife or a toothpick, pierce the stalk in half and tear or cut in half.

  3. Cut the stalk into quarters.

  4. Cover the thinly cut roots with coarse salt and let stand for 10 minutes.

  5. Rinse with water and drain.

  6. Bring a pot of water to boil and quickly blanch the roots. (Dunk them quickly and remove).

  7. Drain the roots and squeeze to remove any remaining water.

  8. Heat up a frying pan over medium heat with the vegetable oil.

  9. Add the bellflower roots to the pan and add garlic, sesame oil, salt, and a dash of sesame salt.

  10. Saute for a few minutes, stirring to combine with seasonings.

Some Information about the Bellflower Root:

"Platycodon grandiflorus (from Greek "πλατυκώδων," meaning a broad bell) is a species of herbaceous flowering perennial plant of the family Campanulaceae and the only member of its genus. It is native to East Asia (China, Korea, Japan and East Siberia). This species is known as platycodon.

Depending upon the region, it is also referred to as the Korean Bellflower, Chinese Bellflower, Japanese Bellflower, common balloon flower, or balloon flower (referring to the balloon-shaped flower buds).

In Korea, the plant is known as doraji (도라지) and its root, either dried or fresh, is a popular ingredient in salads and traditional cuisine. The Chinese bellflower is also used in traditional Chinese medicine.

The extracts and purified platycoside compounds (saponins) from the roots of Platycodon grandiflorum may exhibit neuroprotective, antimicrobial, anti-inflammatory, anti-cancer, anti-allergy, and improved insulin resistance properties. 

Evidence for these potential effects was mainly observed in vitro, with the exception of cholesterol lowering effects documented in vitro and rats. The lack of efficacy and limited safety data in humans, however, necessitates further research.

In Korea, the roots are commonly used for treating bronchitis, asthma, tuberculosis, diabetes, and other inflammatory diseases. In China, they are used as a cough suppressant and expectorant for common colds, cough, sore throat, tonsillitis, and chest congestion.
