Anchovy-Kelp Stock (멸치 육수 — Myeolchi Yuksu)
Every kimchi jjigae recipe on this site calls for “anchovy-kelp stock, or water” — this is that stock. Two dried ingredients, one 20-minute simmer, and the single biggest flavour upgrade you can make to any Korean soup or stew you cook at home.
What Is Myeolchi Yuksu?
Myeolchi yuksu — 멸치 육수 — is a Korean stock made by simmering dried anchovies and dashima (dried kelp) in water for 15-20 minutes, then straining. It’s the standard broth base underneath kimchi jjigae, doenjang jjigae, and most Korean soups — the same role dashi plays in Japanese cooking. The two things that determine whether it tastes clean or bitter: removing the anchovies’ heads and black innards before simmering, and pulling the kelp out after about 5 minutes rather than leaving it in the whole time. Get both right and you get a deeply savoury, genuinely versatile stock in under half an hour, for about 15 calories per cup.
Why This Stock Matters — The Umami Science
This isn’t a “nice to have” upgrade — it’s the difference between a jjigae that tastes complete and one that tastes like it’s missing something.
Umami — the “fifth taste” alongside sweet, salty, sour, and bitter — comes primarily from glutamate, an amino acid found naturally in kelp, tomatoes, parmesan, and many fermented foods. On its own, glutamate gives a pleasant savoury depth. But food scientists have found that when glutamate is combined with a second compound called inosinate — found in dried fish, meat, and mushrooms — the resulting umami sensation isn’t just additive, it’s synergistic: several times stronger than either compound alone.
That’s exactly the pairing at work here. Dashima supplies the glutamate; dried anchovies supply the inosinate. It’s the same principle behind Japanese dashi (kelp plus bonito flakes) and one of the reasons both cuisines converged on nearly identical stock-building logic independently — kelp-plus-dried-fish is simply a very effective way to build deep savoury flavour without meat.
Quick-Simmer vs Cold-Brew — Two Methods Compared
Both produce a legitimate stock — the difference is time invested versus how clean and light the final flavour is.
- Toast anchovies, then simmer with kelp and water for 15-20 minutes total
- Ready in under 25 minutes, no advance planning required
- Slightly more assertive, “cooked” flavour — the toasting step adds roasted depth
Best for: Same-day cooking, weeknight jjigae, most home cooks most of the time.
- Anchovies and kelp steep in cold water in the fridge for 8-12 hours, no heat
- Produces a noticeably cleaner, less fishy-tasting stock
- Requires planning a day ahead; slightly less concentrated than the simmered version
Best for: Delicate soups where you want stock flavour in the background, not the foreground.
Key Terms & Semantic Entities
Which Anchovies to Use — Ranked
Dried anchovies are sold in several sizes for different purposes — using the wrong size is a common reason home stock tastes weak or off.
The standard size sold specifically for stock-making in Korean grocery stores, often labelled “육수용 멸치” (stock-use anchovies). Gives the strongest, most balanced result.
Correct Choice
Sold for side dishes like myeolchi bokkeum, not stock. Usable in a pinch, but gives a milder, less rounded result — use more of them by weight if it’s all you have.
Usable, Not Ideal
Teabag-style packets combining anchovy, kelp, and dried shrimp or radish, sold specifically for convenience. A reasonable shortcut, though the ratio isn’t adjustable.
Convenience Option
A fast, no-strain shortcut — a spoonful stirred directly into hot water approximates the flavour, though it lacks the clarity and depth of a properly simmered stock.
Fastest, Least AuthenticIngredient Ratios — Light vs Strong Stock
The same two ingredients, scaled differently, produce a noticeably different stock — match the ratio to what you’re using it for.
| Stock Strength | Dried Anchovies | Dashima | Water | Best For |
|---|---|---|---|---|
| Light | 6-8 pieces | 1 small piece (7cm) | 5 cups | Clear soups, kimchi guk, delicate dishes |
| Standard ⭐ | 10-12 pieces | 1 piece (10cm) | 5 cups | Kimchi jjigae and most stews — this recipe’s default |
| Strong | 15-18 pieces | 2 pieces (10cm) | 5 cups | Doenjang jjigae, budae jjigae, dishes with bold competing flavours |
How Difficult Is This Stock?
Genuinely one of the easiest things in Korean cooking — the only real skill is timing the kelp correctly.
Equipment
No special equipment required — this is one of the more accessible techniques in Korean home cooking.
| Equipment | Why You Need It | Substitute |
|---|---|---|
| Heavy Pot | Even heat prevents scorching the anchovies during the toast step | Any pot works — a thin one just needs closer attention |
| Fine Mesh Strainer | Removes anchovy and kelp solids for a clear stock | A regular colander lined with a paper towel or cheesecloth |
| Cheesecloth (optional) | Produces the clearest possible stock for delicate soups | Not required for jjigae and stew use — a fine strainer alone is enough |
Ingredients + Scaler
Two dried ingredients and water — makes about 4 cups, enough for one batch of any jjigae recipe in this silo.

How to Make Anchovy-Kelp Stock — 4 Steps
Remove the heads and split each anchovy open to pull out the black innards — this is the main source of bitterness in a poorly-made stock. Optional but genuinely worth the minute or two it takes.
Dry-toast the cleaned anchovies in the pot over medium heat for 1-2 minutes, stirring, until fragrant. This removes raw fishy notes and deepens the umami.
Add the water, dashima, and any optional aromatics. Bring to a simmer, then remove the dashima after 5 minutes — leaving it in longer makes the stock slimy and bitter. Continue simmering the anchovies alone for 10-15 more minutes.
Strain through a fine mesh sieve, pressing lightly on the solids to extract the liquid, then discard the solids. Use immediately, or cool and refrigerate.

Anchovy-Kelp Stock FAQ — 10 Questions
Myeolchi yuksu is a Korean stock made by simmering dried anchovies and dashima (dried kelp) in water. It is the standard broth base for kimchi jjigae, doenjang jjigae, and most Korean soups.
Yes, though the stock will taste slightly more bitter and fishy. Removing the heads and black innards takes under a minute per anchovy and noticeably cleans up the flavour.
Dashima releases its flavour quickly, and simmering it too long causes it to turn slimy and release a bitter, sulfurous taste. Five minutes is enough to extract the glutamate.
They’re closely related — both rely on the same glutamate-inosinate umami combination. Japanese dashi typically uses bonito flakes, while Korean myeolchi yuksu uses whole dried anchovies, giving a slightly stronger, more savoury result.
Yes. It keeps in the fridge for up to 4 days or in the freezer for up to 3 months. Freezing in ice cube trays makes it easy to portion out small amounts for individual recipes.
Yes — a kelp-only stock (dashima yuksu), sometimes with added dried shiitake mushrooms for extra umami, is a common substitute that skips the anchovies entirely.
Medium to large dried anchovies (about 5-7cm) are standard for stock — they give a stronger, more savoury result than the smallest anchovies, which are better suited to side dishes like myeolchi bokkeum.
Yes, and several recipes on this site note it as an option — but the broth will taste noticeably flatter. This stock is the single biggest flavour contributor in most Korean jjigae and soups.
Usually from boiling too vigorously rather than simmering gently, or from not straining thoroughly. A hard boil breaks down more particulate matter from the anchovies into the liquid.
Instead of simmering, anchovies and kelp are steeped in cold water in the refrigerator overnight (8-12 hours). It produces a cleaner, less fishy-tasting stock, though slightly less concentrated than the quick-simmer method.
