Korean Perilla Seed Noodle Soup (Deulkkae Guksu)
A nutty, creamy cold noodle dish made with ground perilla seeds and chilled broth.
About This Recipe
Deulkkae guksu uses ground perilla seeds blended into a broth to create a rich, nutty, slightly creamy base for chilled noodles, a specialty especially associated with Korea's Gangwon province where perilla is widely grown. It's distinct from sesame-based Korean noodle dishes, with perilla's flavor being earthier and more herbal. Straining the ground perilla seed mixture thoroughly is important to get a smooth broth rather than a gritty one — the seeds need to be blended finely and passed through a fine strainer before combining with the other broth ingredients.

Blend the perilla seeds
Blend toasted perilla seeds with water until as smooth as possible, about 2-3 minutes.
- 2
Strain the mixture
Pass the blended mixture through a fine strainer or cheesecloth, pressing to extract all the liquid and discarding the solids.
Strain thoroughly — any remaining grit will make the broth unpleasantly sandy.

Season the broth
Combine the strained perilla liquid with chilled vegetable stock, soy sauce, and salt. Chill in the refrigerator until cold.
- 4
Cook the noodles
Boil wheat noodles according to package directions until tender, then rinse thoroughly under cold water to cool and remove excess starch.

Divide noodles among bowls and ladle the chilled perilla broth generously over the top.
- 6
Garnish and serve
Top with cucumber, scallions, and sesame seeds. Serve immediately while cold.

Pro Tips
- →
Toast the perilla seeds lightly before blending to bring out their nutty flavor more fully.
- →
Strain the blended mixture thoroughly, ideally twice, for the smoothest possible broth.
- →
Chill the broth fully before serving — this dish is meant to be eaten cold, especially in summer.
Variations
- •
Add shredded chicken or a soft-boiled egg for a heartier version.
- •
Mix in sesame seeds or sesame paste alongside the perilla for a blended nutty flavor.
- •
Use buckwheat noodles for a different texture and flavor pairing.
Storage
Store broth and noodles separately; the broth keeps 2 days refrigerated, but cook noodles fresh each time since they clump when stored dressed.
