Annyeonghaseyo, dear readers! It’s your friend from the Korean Recipe Lab here in bustling Seoul. Today, we’re diving into a recipe that, if you truly want to unlock the flavors of authentic Korean home cooking, you absolutely must master: Korean Anchovy-Kelp Broth, or as we call it, myeolchi yuksu (멸치 육수). This isn’t just an ingredient; it’s the very soul of countless Korean dishes. Think of it as the foundational magic that makes everything from comforting stews to refreshing soups sing with that unmistakable Korean umami.
In my family, just like in most Korean households, myeolchi yuksu is made almost weekly. It’s the base for our beloved kimchi jjigae (kimchi stew), doenjang jjigae (fermented soybean paste stew), spicy noodle soups like kalguksu, and even the dipping sauce for our steamed eggs. When you walk into a Korean home and smell something delicious simmering, chances are, this broth is part of the secret!
Many outside Korea rely on store-bought stocks or even just water for their Korean cooking, but trust me, nothing compares to the depth and complexity of homemade anchovy-kelp broth. It adds a clean, oceanic savoriness that elevates every dish it touches. And the best part? It’s incredibly simple to make! This version focuses on getting the purest flavor extraction without any bitterness, using techniques passed down through generations. It’s designed to be approachable even if you’re new to these ingredients, ensuring you get that authentic Korean taste right in your own kitchen.
Ingredients
- 15-20 large dried anchovies (멸치, myeolchi), about 50g (1.7 oz), specifically for broth (look for “soup anchovies” or “broth anchovies”)
- 1 piece dried kelp (다시마, dashima), about 10×10 cm (4×4 inches)
- 1 medium yellow onion, about 150g (5.3 oz), unpeeled, cut in half (optional, for extra sweetness and depth)
- 1 small piece Korean radish (무, mu), about 100g (3.5 oz), or daikon radish, peeled and thickly sliced (optional, for natural sweetness and freshness)
- 2-3 dried shiitake mushrooms (표고버섯, pyogo beoseot) (optional, for additional umami)
- 1.5 liters (6 cups) cold water
Substitutions
Finding good quality dried anchovies and kelp is really the key to this broth. Most regular Western grocery stores won’t carry them, but don’t fret! You can almost always find them at a well-stocked Asian grocery store. Look for them in the dried goods aisle, often near dried mushrooms or seaweed. Online retailers like Amazon are also a great resource. While there aren’t perfect substitutes, here are a few ideas if you’re in a pinch:
- Dried Anchovies (Myeolchi): There’s no true substitute for the unique savory, slightly fishy umami of dried anchovies. If you absolutely cannot find them, you might try a very light, clear fish stock, but be aware the flavor profile will be quite different, lacking the distinct Korean character. It’s genuinely worth seeking out the proper anchovies for an authentic taste.
- Dried Kelp (Dashima): Similar to anchovies, dashima provides a specific kind of clean, oceanic umami that is hard to replicate. If you’re really stuck, a few extra dried shiitake mushrooms can add some umami depth, but the overall flavor will be less distinctly ‘Korean broth’ and more mushroom-forward. Again, I highly recommend finding dashima from an Asian market or online.
- Korean Radish (Mu): If Korean radish or daikon radish is hard to find, a piece of regular white radish or even a small turnip could offer a similar mild sweetness and earthy note, though the texture and intensity of flavor will differ slightly.
- Dried Shiitake Mushrooms: These are usually easier to find in most larger supermarkets or health food stores. If not, you can omit them, but you’ll miss out on some of that extra layer of earthy umami.
How to Make It
-
Prepare the Anchovies: First things first, we need to clean our anchovies. Take each dried anchovy and gently pinch off its head. Then, tear the body open lengthwise and remove the dark guts, which are usually a thin, black line. Why we do this: The heads and guts can introduce a bitter taste to your broth, especially if they are larger anchovies. Removing them ensures a clean, pure, and sweet-tasting broth. Small anchovies might not need this, but for the large ones used in broth, it’s a crucial step.
-
Toast the Anchovies: Place the cleaned anchovies in a dry, non-stick pan over medium-low heat. Toast them gently for about 3-5 minutes, stirring occasionally, until they smell fragrant and slightly crisp. You might see a little smoke, which is normal. Why we do this: This dry roasting step is a home cook’s secret! It helps to remove any lingering fishiness and deepen the savory flavor of the anchovies, giving your broth a much richer aroma and taste.
-
Prepare the Kelp and Aromatics: While the anchovies are toasting, gently wipe the dried kelp (dashima) with a clean, damp cloth. Why we do this: There might be some white powdery residue on the kelp, which is actually naturally occurring glutamates (umami!). You want to wipe off any dust or impurities, but don’t rinse it under running water or scrub it vigorously, as you’ll wash away those precious umami compounds. If using, halve the onion, slice the radish, and add the dried shiitake mushrooms to your pot.
-
Combine Ingredients with Cold Water: Transfer the toasted anchovies and kelp (along with optional onion, radish, and shiitake) into a large pot. Pour in 1.5 liters (6 cups) of cold water. Why cold water? Starting with cold water allows for a gradual and gentle extraction of flavors from the anchovies and kelp. If you start with hot water, the proteins can seize up, resulting in a cloudy broth and less flavor extraction.
-
Simmer and Remove Kelp: Bring the water to a boil over medium-high heat. As soon as it comes to a rolling boil, reduce the heat to low, cover the pot partially, and let it simmer gently for about 10 minutes. At this point, carefully remove the piece of dried kelp from the pot using tongs. Why remove the kelp after 10 minutes? Kelp is fantastic for a quick burst of umami, but if it simmers for too long, it can release a slimy texture and a slightly bitter taste, which will compromise the clean flavor of your broth.
-
Continue Simmering: Continue to simmer the broth, uncovered, for another 10-15 minutes. Why continue simmering? Removing the kelp allows the anchovies to continue releasing their deep, savory flavors without the risk of the broth becoming slimy or bitter. Simmering for this extended period ensures maximum flavor extraction from the anchovies and optional vegetables, concentrating the broth’s delicious essence.
-
Strain the Broth: Once the simmering time is complete, remove the pot from the heat. Carefully strain the broth through a fine-mesh sieve into a clean bowl or container. Discard all the solids (anchovies, onion, radish, shiitake). Why strain? This ensures you have a perfectly clear, clean broth, free of any debris, ready to be used as a base for your Korean dishes.
Tips from a Korean Kitchen
- Don’t Wash Anchovies or Kelp: Unlike some ingredients, you shouldn’t wash dried anchovies or kelp under running water. As explained, washing kelp removes its precious umami-rich white powder, and anchovies are dry-roasted, not rinsed.
- Size Matters for Anchovies: For broth, look for larger, silver-colored dried anchovies (sometimes labeled ‘soup anchovies’). Smaller anchovies are typically for stir-fries or side dishes and have a different flavor profile.
- No Over-Boiling Kelp: This is perhaps the most crucial tip! Over-boiling kelp is the quickest way to ruin your broth by making it slimy and bitter. Always remove it after 10-15 minutes of simmering once the water boils.
- Don’t Be Afraid of the “Fishy” Smell: When you’re cleaning or toasting the anchovies, they might have a strong, distinct smell. Don’t worry! This is normal. The roasting process and subsequent simmering will transform that smell into a wonderfully savory, clean aroma in the finished broth.
Storage
Korean anchovy-kelp broth is excellent for making ahead! Let it cool completely to room temperature before storing. In the refrigerator, it will keep well in an airtight container for up to 3-4 days. For longer storage, you can freeze it in individual portions (ice cube trays are great for this, or freezer-safe bags) for up to 3 months. When ready to use, simply thaw in the refrigerator overnight or gently reheat from frozen in a pot over low heat.
FAQ
Can I skip cleaning the anchovies?
While you might be tempted to skip cleaning the anchovies (removing the heads and guts) for convenience, I strongly advise against it for broth. The heads and especially the dark guts contain compounds that will make your broth bitter and cloudy, overpowering the delicate umami you’re trying to achieve. It takes only a few minutes and makes a significant difference in the final taste.
What if I don’t have dried kelp (dashima)? Can I still make the broth?
You can still make a decent anchovy broth without kelp, but it won’t have the same depth and balanced umami. Kelp adds a specific clean, oceanic sweetness that is characteristic of Korean broths. If you absolutely can’t find it, using extra dried shiitake mushrooms can add some umami, but the overall flavor profile will shift. For an authentic taste, it’s worth the effort to source dashima.
How long does this broth take to make?
The active cooking time for Korean anchovy-kelp broth is surprisingly quick, usually around 20-30 minutes. This includes a few minutes for cleaning and toasting the anchovies, 10 minutes for simmering with kelp, and another 10-15 minutes for simmering the anchovies alone. The resting and straining add a little extra time, but it’s a very efficient way to build a flavor foundation for your meals!
