Among all types of jeotgal (Korean salted and fermented seafood), saeujeot (새우젓, salted shrimp) holds a special place on the Korean dining table.
It’s the most widely used and versatile kind — a condiment, a seasoning, and even a side dish in its own right.
(For more background on Korean fermented seafood, see [The Salty Secret of Korean Cuisine: The World of Jeotgal].)
What Is Saeujeot?
Saeujeot is made by fermenting small shrimp in coarse sea salt.
Over time, the shrimp break down naturally, producing a salty, savory, and slightly briny liquid that adds deep umami to almost any dish.
It’s one of the oldest and most essential seasonings in Korean cuisine, found in everything from soups to kimchi.
Unlike liquid fish sauces such as aekjeot, saeujeot retains the shrimp’s texture — soft, semi-transparent, and richly flavored.
Its aroma may be strong to those unfamiliar with fermented foods, but once tasted, it reveals a delicate, oceanic sweetness beneath the salt.
The Role of Saeujeot in Korean Cuisine
1. A Must-Have Condiment for Meat Dishes
Saeujeot is the perfect match for boiled or roasted pork, especially in classic Korean dishes like bossam (boiled pork wraps) and jokbal (braised pig’s trotters).
Its salty, slightly funky flavor cuts through the fat and enhances the meat’s richness, creating a well-balanced taste.
Many Korean homes and restaurants prepare a simple saeujeot dipping sauce by mixing it with minced garlic, chili flakes, and sesame oil — a must for any pork feast.
2. An Irreplaceable Ingredient for Kimchi
Perhaps saeujeot’s most famous role is as a key ingredient in kimchi.
When making kimchi, saeujeot provides the fermentation starter, helping beneficial bacteria grow while adding complexity to the flavor.
Its enzymes break down proteins in vegetables, deepening the umami as the kimchi matures.
Without saeujeot, traditional kimchi simply wouldn’t have its signature depth.
3. A Flavorful Side Dish — Saeujeot Muchim
While it’s most often used as seasoning, saeujeot can also be enjoyed as a side dish by itself.
Koreans make Saeujeot Muchim, a simple mix of salted shrimp with chili flakes, sugar, minced garlic, and sesame oil.
It’s spicy, salty, and slightly sweet — the perfect companion to a bowl of steamed rice.
Regional Specialties: Ganggyeong and Gwangcheon
Saeujeot’s quality depends heavily on where and how it’s fermented, and certain regions of Korea are famous for producing the best.
-
Ganggyeong (강경):
Located along the Geum River, this town has long been known for its ideal fermentation environment — mild temperatures, coastal breezes, and clean salt.
Ganggyeong saeujeot is prized for its clean, balanced flavor and subtle aroma. -
Gwangcheon (광천):
Situated near the West Sea, Gwangcheon produces shrimp with slightly larger bodies and firmer textures.
The result is a richer, more intense saeujeot, perfect for kimchi-making and long-term storage.
These regional varieties are so distinct that saeujeot is often sold with the producer’s location proudly labeled on the jar — a mark of authenticity and local pride.
How Saeujeot Is Made
The process of making saeujeot is simple yet precise.
Fresh shrimp are caught during peak season (usually from late spring to early fall), then immediately mixed with coarse salt — typically 20–30% of the shrimp’s weight.
The salted shrimp are placed into large earthenware jars (onggi) and left to ferment for several months, exposed to sunlight during the day and cooled by sea breezes at night.
The natural enzymes in shrimp break down over time, producing amino acids that form the deep umami flavor Koreans love.
During this fermentation, the mixture transforms — from raw shrimp into a pinkish, semi-liquid paste that’s both savory and aromatic.
Once aged to perfection, saeujeot is stored in cool cellars or refrigerators and can keep for many months due to its high salinity.
Making Saeujeot at Home
While traditional saeujeot requires a coastal climate, large fermentation jars, and months of careful aging, it’s still possible to make a small-batch version at home that captures the essence of its flavor.
The key is to use fresh shrimp, the right salt ratio, and cool fermentation conditions.
Ingredients
-
1 pound (450 g) of small shrimp (fresh or previously frozen, raw and unpeeled)
-
5–6 tablespoons of coarse sea salt (about 20–25% of shrimp weight)
-
A clean glass jar or earthenware container with a tight lid
Instructions
-
Prepare the Shrimp
Rinse the shrimp gently under cold water and drain thoroughly.
Avoid using cooked or seasoned shrimp — they won’t ferment properly. -
Mix with Salt
In a bowl, combine shrimp and sea salt evenly.
Stir gently to coat every piece, but don’t crush the shrimp. -
Pack and Seal
Transfer the salted shrimp into a clean, sterilized glass jar.
Press them down slightly to remove air pockets, then seal the lid tightly. -
Ferment Slowly
Place the jar in a cool, dark place (around 10–15°C / 50–60°F) for 2–3 weeks.
If the environment is too warm, fermentation can accelerate and turn overly strong or sour.
In cooler climates, it may take longer — up to a month. -
Refrigerate and Age
After the initial fermentation, move the jar to the refrigerator to slow the process.
The flavor will continue to mature gradually over time.
Notes and Tips
-
Salt ratio matters: Too little salt causes spoilage; too much makes it inedibly salty. The sweet spot is about 20–25% of the shrimp’s weight.
-
Temperature control: Warm conditions make saeujeot ferment too fast and can produce bitterness. Cool, stable temperatures are ideal.
-
Storage: Once fermented, saeujeot can be kept refrigerated for several months or frozen for even longer.
Homemade saeujeot won’t be exactly like the traditional versions from Ganggyeong or Gwangcheon, but it gives you a taste of Korea’s time-honored fermentation techniques — right in your own kitchen.
It’s also a wonderful way to understand the balance of salt, temperature, and time that defines Korean culinary heritage.
The Versatility of Saeujeot in Everyday Cooking
Saeujeot’s ability to enhance flavor makes it one of the most useful condiments in the Korean pantry.
Here are some popular ways it’s used:
-
Kimchi seasoning: The backbone of authentic kimchi flavor.
-
Soup and stew base: Adds umami depth to dishes like doenjang jjigae or kimchi jjigae.
-
Vegetable side dishes (namul): A small spoonful can season spinach, bean sprouts, or watercress perfectly.
-
Dipping sauce: Mixed with chili powder, garlic, and sesame oil for meat dishes.
-
Saeujeot Fried Rice: Stir-fried with rice, green onions, and a touch of butter for a unique, salty-savory meal.
Even a small amount goes a long way — a true testament to its concentrated flavor.
Storing Saeujeot
Because of its high salt content, saeujeot keeps well for a long time, especially when refrigerated.
For longer storage, many Koreans divide it into small containers and freeze them to maintain freshness.
This allows you to take out only what you need — a spoonful at a time — while preserving the rest.
A Living Tradition on the Korean Table
Saeujeot is more than just fermented shrimp — it’s a living symbol of Korean food culture.
It represents the wisdom of preservation, the respect for nature’s cycles, and the art of fermentation that defines so much of Korean cuisine.
Today, saeujeot continues to evolve: from traditional clay jars in Ganggyeong and Gwangcheon to neatly packaged products for global kitchens.
Yet, its essence remains unchanged — a spoonful of deep, ocean-born umami that connects the modern palate to centuries of Korean culinary heritage.
