Korean Anchovy
When you walk into a Korean home kitchen, one ingredient almost certainly occupies a permanent spot in the freezer: dried anchovies. Known as myeolchi (멸치) in Korean, these small, silvery fish serve as the backbone of countless dishes, from the clear, savory broths that warm cold winter nights to the sweet and crunchy side dishes tucked into children’s lunchboxes. Understanding Korean anchovy opens the door to authentic Korean cooking, where umami-rich flavors develop through simple, time-honored techniques passed down through generations.
Unlike Western cured anchovies packed in oil and salt for pizza toppings, Korean dried anchovies undergo a different transformation altogether. Fresh anchovies are boiled briefly in seawater and then sun-dried, a preservation method that concentrates their savory essence while creating a shelf-stable pantry staple. This processing technique yields fish with clean, subtle flavor that enhances rather than overwhelms other ingredients—making them remarkably versatile in the Korean kitchen.

Understanding Korean Anchovy Sizes and Their Specific Uses
Korean culinary tradition categorizes dried anchovies by size, with each category serving distinct culinary purposes. This size-based classification reflects the sophisticated approach Korean cooking takes toward maximizing flavor extraction and textural enjoyment from a single ingredient.
Large Anchovies (Gukmulyong Myeolchi, 국물용 멸치) measure approximately 7-10 centimeters in length. These substantial fish contain more flesh and fat, making them ideal for creating rich, complex broths. Home cooks typically remove the heads and dark intestines before simmering to prevent bitterness in the final stock.
Medium Anchovies (Jungan Myeolchi, 중간 멸치) span roughly 5-7 centimeters and occupy a versatile middle ground. They work well for lighter stocks and can also be prepared as side dishes when cleaned properly. Many Korean families prefer this size for everyday cooking because of its flexibility.
Small Anchovies (Bokkeum Yong Myeolchi, 볶음용 멸치) measure between 3-5 centimeters and are specifically labeled for stir-frying. Their smaller size means they can be eaten whole, bones and all, delivering concentrated nutrition in every bite.
Tiny Anchovies (Jiri Myeolchi, 지리멸치) represent the smallest category at under 2 centimeters. These delicate fish require no preparation beyond a quick pan-toast and are popular in seasoned side dishes where their subtle crunch adds textural interest without overwhelming fishiness.
Why Do Koreans Use Different Anchovy Sizes?
The Korean approach to dried anchovy reflects a deeper culinary philosophy: matching ingredient characteristics to cooking applications maximizes both flavor and nutritional benefit. Larger anchovies possess more surface area and fat content, which means longer simmering extracts deeper umami compounds into broths. Their robust structure withstands extended cooking without disintegrating.
Smaller anchovies, conversely, would turn mushy in long-simmered broths but shine when quickly stir-fried with sweet and savory sauces. Their thin bodies absorb glazes beautifully while maintaining appealing crunch. The soft, edible bones in smaller varieties provide concentrated calcium and minerals that Korean families particularly value for growing children.
This size-differentiated approach extends to how anchovies are packaged and sold. Korean markets clearly label packages as either "gukmul yong" (for broth) or "bokkeum yong" (for stir-frying), eliminating guesswork for home cooks. Understanding this system helps international cooks select appropriate anchovies for their intended dishes.
Making Authentic Korean Anchovy Broth (Myeolchi Yuksu)
Korean anchovy broth, called myeolchi yuksu (멸치육수), forms the foundation for countless Korean soups, stews, and sauces. Unlike Western fish stocks that require hours of simmering, this Korean version comes together quickly while delivering remarkable depth of flavor. The resulting broth tastes clean and subtly savory rather than overtly fishy—a testament to the quality of properly dried anchovies.
Basic Anchovy-Kelp Stock Method:
Start with about 8-10 large dried anchovies for every 6-8 cups of water. Split each anchovy and remove the dark intestines and head, which can contribute bitter notes. Combine the prepared anchovies with a 3-inch square of dried kelp (dashima) in a pot. For deeper understanding of how kelp contributes to Korean cooking, explore our guide to Korean kelp (dashima).
Bring the water to a gentle simmer rather than a rolling boil—aggressive boiling can make kelp slimy and extract harsh flavors from the anchovies. Simmer uncovered for 15-20 minutes, then strain out the solids. The resulting golden-hued broth serves as the base for doenjang jjigae, tteokbokki, sundubu jjigae, and many other Korean classics.
Cold-Soak Method for Enhanced Flavor:
For even more nuanced flavor, try the cold-soak method that many Korean grandmothers prefer. Place prepared anchovies and kelp in cold water and refrigerate overnight or for at least 4 hours. This gentle extraction pulls out subtle flavors without any risk of bitterness. Simply heat the soaked mixture before using, or use directly in recipes that will be cooked.
Myeolchi Bokkeum: Korea’s Beloved Stir-Fried Anchovy Side Dish
Few banchan (Korean side dishes) appear as consistently on Korean tables as myeolchi bokkeum (멸치볶음). This sweet, savory, and slightly sticky preparation transforms humble dried anchovies into an irresistible accompaniment to rice. Korean mothers pack it in lunchboxes, knowing children will eat their entire meal just to get to the anchovies.
The dish requires small to medium dried anchovies, which are first toasted in a dry or lightly oiled pan to remove moisture and develop nuttiness. A sauce typically combines soy sauce, rice syrup or honey, garlic, and often gochujang for a spicy variation. The anchovies return to the pan with the sauce, cooking until each piece is glossy and coated. Finished with sesame oil and toasted sesame seeds, myeolchi bokkeum keeps well refrigerated for up to a week.
Common Variations:
- Myeolchi-ttangkong-bokkeum adds roasted peanuts for extra crunch and protein
- Spicy myeolchi bokkeum incorporates gochugaru (Korean red pepper flakes) or gochujang
- Myeolchi-muchim seasons tiny anchovies without cooking for a quick, crunchy side dish
Understanding how this dish fits within Korean meal traditions offers insight into the broader banchan culture that makes Korean dining distinctive.
Korean Anchovy Fish Sauce and Fermented Products
Beyond dried applications, Korean anchovies transform through fermentation into powerful umami-building condiments. Myeolchi aekjeot (멸치액젓), Korean anchovy fish sauce, results from months of fermenting salted anchovies until they break down into a clear, amber liquid. This ingredient serves essential roles in kimchi-making, where it accelerates fermentation while adding depth that plain salt cannot achieve.
The fermentation science behind myeolchi aekjeot involves halophilic (salt-loving) bacteria that thrive in the approximately 25% salt environment. Research published in the International Journal of Food Microbiology found that different anchovy sizes produce fish sauce with varying fermentation patterns and flavor profiles, with smaller anchovies fermenting more quickly than larger ones.
Myeolchi jeot (멸치젓), the whole fermented anchovy preparation, appears in regional Korean cooking as both a kimchi ingredient and a condiment. The Chuja Islands between mainland Korea and Jeju are renowned for producing premium quality salted anchovies prized by kimchi-makers throughout the country.
For those exploring Korean fermented foods more broadly, our guide to kimchi and the fermentation process explains how these anchovy products contribute to Korea’s rich fermentation tradition.
Nutritional Benefits of Korean Anchovies
Korean families have long encouraged children to eat anchovies for strong bone development, and modern nutritional science validates this traditional wisdom. Eating dried anchovies whole—bones included—delivers exceptional calcium content that supports skeletal health throughout life.
Key Nutrients in Korean Dried Anchovies:
- Calcium: Approximately 147mg per 100g serving, supporting bone density and dental health
- Protein: About 20g per 100g, providing complete amino acids for muscle maintenance
- Omega-3 Fatty Acids: EPA and DHA support cardiovascular and brain health
- Selenium: Important for thyroid function and antioxidant protection
- Iron: Supports oxygen transport throughout the body
The omega-3 content in anchovies deserves particular attention. These essential fatty acids help reduce inflammation, support heart health, and contribute to cognitive function. Because anchovies sit low on the marine food chain, they accumulate minimal heavy metals compared to larger fish, making them a safer choice for regular consumption.
Dried anchovies also provide vitamin D, a nutrient many people lack, especially those living in northern climates. The combination of calcium and vitamin D makes anchovies particularly effective for bone health, as vitamin D enhances calcium absorption.
How Should You Store Korean Dried Anchovies?
Proper storage ensures your dried anchovies maintain quality and flavor for months. Despite being dried, these fish contain residual oils that can oxidize and turn rancid if stored improperly. Korean home cooks universally recommend freezer storage as the gold standard.
Best Storage Practices:
Transfer dried anchovies to an airtight container or heavy-duty freezer bag, removing as much air as possible. Stored in the freezer, they maintain quality for up to one year. The freezing process doesn’t significantly alter their texture because the low moisture content prevents ice crystal formation.
Refrigerator storage works for shorter periods of 2-3 months, particularly useful if you use anchovies frequently and want easy access. Avoid pantry storage except for immediate use, as humidity and warmth accelerate quality degradation.
Signs that anchovies have deteriorated include yellowing color (fresh ones appear silvery-blue), strong off-odors, or visible mold. While slightly yellowed anchovies remain safe for broth-making, their flavor has diminished. Always inspect anchovies before using, discarding any that show signs of spoilage.
Where to Buy Quality Korean Anchovies
Quality Korean anchovies feature clean, silvery skins with a bluish tone, indicating freshness and proper processing. The best specimens come from Korea’s southern coastal waters, particularly areas around Tongyeong and the southern peninsula where clean ocean conditions and traditional processing methods persist.
Shopping Tips:
Korean grocery stores offer the widest selection, with dedicated freezer or refrigerator sections containing multiple sizes and brands. Look for packages clearly labeled with size designations (gukmul yong or bokkeum yong) and check production dates when possible.
Online retailers increasingly stock quality Korean anchovies, though shipping frozen or refrigerated products adds complexity. Reputable Korean food e-commerce sites maintain proper cold chain protocols, but always verify their shipping methods before ordering.
Asian supermarkets beyond Korean specialty stores typically carry dried anchovies, though selection may be limited to one or two sizes. Japanese dried anchovies (iriko or niboshi) make acceptable substitutes when Korean varieties aren’t available, though flavor profiles differ slightly.
Cooking Tips for First-Time Users
Starting with Korean dried anchovies can feel intimidating for cooks unfamiliar with this ingredient, but a few simple guidelines ensure success.
For Broth-Making:
- Always remove heads and intestines from large anchovies to prevent bitterness

🩺 Dr.’s Nutritional Insight
Anchovies are one of the richest dietary sources of the omega-3 fatty acids EPA and DHA, which play a direct role in skin barrier integrity. These fatty acids integrate into epidermal cell membranes, reducing transepidermal water loss and modulating inflammatory pathways by competing with pro-inflammatory omega-6 metabolites. A comprehensive review in the International Journal of Molecular Sciences found that EPA and DHA downregulate cytokines like TNF-α and IL-6, providing measurable photoprotective and anti-inflammatory benefits for the skin (Balić et al., 2020). Consuming anchovies whole also delivers selenium, which supports antioxidant defense systems critical to preventing oxidative skin damage.

This guide covers everything you need to cook authentic Korean fernbrake — from sourcing dried gosari to understanding why it belongs in your bibimbap, and why Korean grandmothers have been keeping it in their pantries for generations.
Korean raw beef dish (Yukhoe)
There are dishes that define a cuisine’s confidence — its willingness to let a single, exceptional ingredient speak for itself. In Korea, yukhoe (육회) is exactly that dish. Made from finely sliced raw beef seasoned with sesame oil, soy sauce, garlic, and sugar, then crowned with a golden egg yolk and fanned with thin sheets of Korean pear, yukhoe is one of the most quietly stunning preparations in Korean cuisine. Yet for many visitors, the words "raw beef" are enough to give pause. This guide is here to change that. Whether you’re curious about the tradition behind this Korean raw beef dish, wondering how it compares to steak tartare, or simply trying to figure out whether it’s safe to eat, you’ll find everything you need right here.
Korean Dumplings (Mandu)
Few dishes in Korean cuisine carry the warmth, history, and everyday versatility of mandu (만두). Whether you have encountered these dumplings tucked into a bubbling bowl of soup, sizzling golden in a pan at a street stall, or folded neatly by a grandmother during the Lunar New Year, mandu represent something deeper than a quick meal. They are a living expression of Korean culinary identity — shaped by centuries of cultural exchange, regional creativity, and family tradition.
For English-speaking food lovers exploring Korean cuisine, mandu are one of the most approachable entry points. The concept is familiar — a thin dough wrapper encasing a savory filling — yet the Korean interpretation is genuinely distinctive: lighter, more vegetable-forward, and rich with the aromatics that define Korean home cooking. This guide covers everything you need to know, from the ingredient secrets inside each dumpling to the best restaurants in Seoul where you can taste them fresh from skilled hands.
Korean Kumquat
When winter settles across the Korean peninsula, small golden fruits no bigger than a walnut begin appearing in markets, gift boxes, and home kitchens. These are kumquats — known in Korean as geumgyul (금귤), meaning "golden citrus," or by the more playful colloquial name kkingkkang (낑깡). Unlike almost every other citrus fruit, Korean kumquat is eaten whole, peel and all, delivering a flavor experience that surprises first-time tasters: the skin is sweet, while the tiny burst of flesh inside carries a refreshing tartness. This delightful contrast has made Korean kumquat a cherished ingredient in homemade syrups, traditional candied sweets, teas, and modern desserts.
For English-speaking home cooks exploring Korean cuisine, kumquat offers an accessible yet distinctive entry point into Korea’s broader tradition of preserving seasonal fruits — the same philosophy that underpins kimchi-making culture and the centuries-old art of balancing sweet, sour, salty, and savory flavors in every Korean meal.
