Eomuk (어묵): Korean Fish Cake Recipe & Street Food Soup Guide
Chewy, savory, and endlessly versatile Korea's favorite fish cake, from the street cart skewer to the comforting soup bowl.
If you've ever stood at a Korean street cart on a cold day, holding a paper cup of hot broth with a skewer of something chewy and golden, you've already met eomuk. It's Korea's most underrated street food humble, cheap, and quietly everywhere.
Eomuk (also spelled odeng or umuk) is a Korean fish cake made from ground white fish, starch, and seasonings, shaped into sheets, cylinders, or balls, then boiled, fried, or simmered. It's the star of eomuk-tang (fish cake soup), the essential companion to tteokbokki, and the secret ingredient in countless Korean home dishes.
What makes eomuk special is its texture: springy, bouncy, and slightly chewy, with a mild seafood sweetness that soaks up whatever broth or sauce it's cooked in. It's not fishy it's savory, satisfying, and deeply comforting. And while store-bought eomuk is widely available, making it at home is surprisingly simple and gives you a fresher, cleaner-tasting result.
This guide covers everything: what eomuk actually is, the different styles, how to make it from scratch, and a detailed recipe for the classic eomuk-tang (fish cake soup) that Korean street vendors serve alongside tteokbokki.
What Is Eomuk, Exactly?
Eomuk is a Korean fish cake made from a paste of ground white fish (usually pollock, cod, or hake), combined with starch (wheat, potato, or tapioca), egg whites, sugar, salt, and sometimes vegetables or seasonings. The mixture is shaped and then cooked either boiled, steamed, or fried until it sets into a firm, springy cake.
It's closely related to Japanese kamaboko and chikuwa, but Korean eomuk is typically softer, chewier, and more mildly seasoned, designed to be used in soups and stir-fries rather than eaten alone.
There are several main styles:
- Square eomuk (사각어묵) flat, rectangular sheets, the most common type. Used in soups and stir-fries.
- Bar eomuk (막대어묵) thick, cylindrical sticks, usually served on skewers in street broth.
- Ball eomuk (동그랑어묵) round balls, often stuffed with vegetables or cheese.
- Fried eomuk (튀긴어묵) deep-fried fish cake, sold as a snack or side dish.
In Korea, eomuk is sold everywhere: at street carts, in supermarkets, and in the frozen section. But homemade eomuk has a cleaner, fresher flavor that's worth the effort.
Why This Recipe Works
Most homemade eomuk fails for one of three reasons: the texture is too dense, the flavor is too fishy, or the cakes fall apart during cooking. This recipe solves all three:
- Ice-cold fish paste keeping the fish and equipment cold prevents the proteins from breaking down and gives the eomuk its signature springy texture.
- The right starch ratio too much starch makes it dense; too little makes it rubbery. The 4:1 fish-to-starch ratio below is the sweet spot.
- A quick steam-then-boil method steaming sets the shape, boiling finishes the texture. This is the traditional Korean technique.
Ingredients (Makes About 8 Sheets of Eomuk)
For the eomuk:
- 400g white fish fillet (pollock, cod, or hake), skinless and boneless
- 100g potato starch or tapioca starch
- 1 egg white
- 1 tbsp sugar
- 1 tsp salt
- 1/2 tsp white pepper
- 1 tbsp rice wine (mirin) or cooking sake
- 1 tsp sesame oil
- 2 tbsp ice-cold water (plus more as needed)
- 1/4 cup finely chopped carrots, onions, or green onions (optional)
For the eomuk-tang (fish cake soup):
- 8 cups water
- 10 dried anchovies (myeolchi), heads and guts removed
- 1 piece dried kelp (dashima), about 4x4 inches
- 1 small radish, sliced
- 1 onion, halved
- 2 tbsp soy sauce
- 1 tsp salt (to taste)
- 1 tsp sugar
- Green onions, sliced (for garnish)
- Optional: Korean red chili pepper, sliced
Note: If you can't find fresh white fish, you can use frozen fish that's been fully thawed and patted dry. Avoid oily fish like salmon or mackerel they don't work for eomuk.
Step-by-Step Recipe
Step 1: Prepare the Fish Paste
Cut the fish into small chunks and place them in a food processor. Add the egg white, sugar, salt, white pepper, rice wine, and sesame oil. Pulse until you have a smooth, sticky paste. Scrape down the sides as needed. The mixture should be very smooth any chunks will show up in the final texture.
Keep it cold: Place the food processor bowl and blade in the freezer for 15 minutes before starting. Cold equipment keeps the fish paste springy instead of mushy.
Step 2: Add the Starch
Add the potato starch to the fish paste and pulse until fully combined. The mixture will become thicker and slightly stiffer. Add the ice-cold water, one tablespoon at a time, until the paste is smooth and spreadable but still holds its shape. If you're using vegetables, fold them in now with a spatula.
Step 3: Shape the Eomuk
Line a baking sheet or steamer basket with parchment paper. Wet your hands with cold water to prevent sticking. Take about 1/4 cup of the fish paste and shape it into a flat rectangle about 1/2 inch thick, or roll it into a cylinder for bar eomuk. Place each piece on the prepared sheet. Repeat with the remaining paste.
Step 4: Steam the Eomuk
Bring a steamer pot of water to a boil. Place the eomuk in the steamer basket, cover, and steam for 10–12 minutes, until the cakes are firm and cooked through. They will look slightly translucent when done. Remove from the steamer and let them cool completely before slicing or using.
Step 5: Make the Eomuk-Tang Broth
In a large pot, combine the water, dried anchovies, kelp, radish, and onion. Bring to a gentle simmer over medium heat do not let it boil hard, or the broth will turn bitter. Simmer for 15 minutes, then remove the anchovies, kelp, radish, and onion. Add the soy sauce, salt, and sugar. Taste and adjust the seasoning.
Step 6: Assemble and Serve
Slice the cooled eomuk into thin strips or bite-sized pieces. Add them to the simmering broth and cook for 3–4 minutes, until heated through and softened. Ladle into bowls and garnish with sliced green onions and optional chili pepper. Serve hot, with steamed rice on the side if you like.
Street cart style: For the classic Korean street experience, thread the eomuk onto skewers before adding to the broth. Serve with a small cup of the hot broth on the side that's how it's done at every pojangmacha in Korea.
Popular Variations to Try
- Eomuk-bokkeum (spicy stir-fried fish cake) stir-fry sliced eomuk with gochujang, soy sauce, garlic, and vegetables. A popular banchan (side dish).
- Cheese eomuk shape the fish paste around a cube of mozzarella before steaming. When fried, the cheese melts into a gooey center.
- Vegetable eomuk add finely chopped carrots, onions, and green onions to the paste for color and flavor.
- Fried eomuk (twigin eomuk) instead of steaming, deep-fry the shaped eomuk at 170°C (340°F) until golden. Crispy outside, springy inside.
- Eomuk skewers with broth the classic street food version: thread eomuk onto skewers, simmer in the anchovy-kelp broth, and serve with a cup of the hot broth.
Tips for the Best Eomuk
- Keep everything cold. Cold fish, cold equipment, and ice water are the secrets to springy eomuk. Warm paste turns dense and rubbery.
- Don't over-process. Once the paste is smooth, stop. Over-processing heats the mixture and breaks down the texture.
- Steam, don't boil. Steaming sets the shape gently. Boiling can make the eomuk waterlogged and crumbly.
- Cool completely before slicing. Warm eomuk is soft and tears easily. Let it cool fully for clean, even slices.
- Use it in everything. Eomuk isn't just for soup add it to tteokbokki, stir-fries, hot pots, and even sandwiches.
Frequently Asked Questions
Is eomuk the same as Japanese kamaboko?
They're related but not identical. Kamaboko is usually firmer and more subtly flavored, often served as a standalone garnish. Eomuk is softer, chewier, and more mildly seasoned, designed for soups and stir-fries.
What fish is best for eomuk?
White fish with a mild flavor and firm texture: pollock, cod, hake, or tilapia. Avoid oily or strong-flavored fish like salmon, mackerel, or tuna.
Can I make eomuk without a food processor?
Yes you can use a blender, or finely mince the fish with a knife and mix vigorously by hand. A food processor gives the smoothest result, but the others work in a pinch.
Why is my eomuk rubbery?
Rubbery eomuk usually means too much starch or over-processing. Stick to the 4:1 fish-to-starch ratio and stop processing as soon as the paste is smooth.
How do I store eomuk?
Store homemade eomuk in the fridge for up to 3 days, wrapped tightly or in an airtight container. For longer storage, freeze for up to 2 months. Thaw in the fridge before using.
The Bottom Line
Eomuk is one of Korea's most versatile and underrated foods. It's the chewy, savory backbone of street food soup, the quiet hero of tteokbokki, and the ingredient that makes a simple broth feel like a meal. And while store-bought eomuk is convenient, homemade eomuk has a freshness and texture that's worth the effort.
Start with the classic eomuk-tang. Get the broth right. Steam the fish cakes gently. And serve it hot, with a skewer and a cup of broth, the way it's meant to be eaten. That's the real Korean street food experience no plane ticket required.
Enjoy your eomuk. And if you make it, share it because this is the kind of food that warms people up from the inside out.
