We reveal two secrets: how to make authentic kongguksu (콩국수) broth by cooking and grinding peeled white soybeans (백태콩) yourself, and a super simple broth that can be made in just 20 minutes using injeolmi (인절미) soybean powder.
📝 Editor's Notes
Here's an original, old-fashioned kongguksu (콩국수) recipe that can be completed in just 30 minutes, using only peeled white soybeans (백태콩) and sōmen (소면) noodles.
Excluding the soybean soaking time, it's surprisingly simple to make.
The savory and rich soy milk broth combined with refreshing noodles makes for a delightful dish that helps you forget the summer heat.
It's a great choice when you're looking for a hearty yet light meal.
Especially when served with vegetables, it provides a perfectly balanced and nutritious meal for the whole family.
🛒 Ingredient Tips
The key ingredient for this kongguksu (콩국수) is white soybeans (백태콩).
While both domestic Seoritae (서리태, black soybeans) or Baektae (백태, white soybeans) are good, using peeled white soybeans can save you the hassle of peeling them after soaking or cooking, thus shortening the preparation time.
When choosing soybeans, look for plump, glossy ones without any signs of insect damage.
For noodles, regular sōmen (소면) noodles, often called traditional sōmen, are ideal; a medium thickness that isn't too thin or too thick pairs well with the soy milk broth.
For cucumbers, choose fresh, firm, and brightly colored ones to add a crisp texture.
🔄 Substitution Guide
If white soybeans (백태콩) are unavailable or if you have an allergy, you can make the soy milk broth using tofu.
Briefly blanching tofu in boiling water can reduce its raw taste, and then blending it with water can easily create a soy milk broth substitute.
However, tofu-based broth tends to have a slightly lighter and cleaner flavor than one made with white soybeans.
Instead of sōmen (소면) noodles, you can use jjolmyeon (쫄면, chewy noodles) or jungmyeon (중면, medium-thick noodles), but note that the noodle thickness and texture will differ, so choose according to your personal preference.
If pine nuts are unavailable, you can use other nuts like peanuts or sunflower seeds as a garnish to add a savory flavor.
🥘 Ingredients
👨🍳 Cooking Points
The most crucial cooking point is the soybean cooking time.
Cooking soybeans for too long can result in a meju (메주)-like smell, while undercooking can lead to a raw, beany odor.
It's important to cook them for about 5 minutes until they have a slightly firm, crunchy texture. Just remember this.
Another tip is not to discard the soybean cooking water but to blend it along with the soybeans.
This water concentrates the nutrients and savoriness of the soybeans, enhancing the rich flavor of the broth.
Finally, when blending the soy milk broth, add the cooked soybeans and cooled soybean cooking water gradually to the blender and blend in 30-second intervals multiple times to achieve a smooth consistency.
👨🍳 Directions
Soak 2 cups of peeled white soybeans (백태콩) for 5 hours, then rinse thoroughly several times.
Bring water to a boil, add the soybeans, and cook for about 5 minutes. Cooking too long can result in a meju (메주)-like smell, while undercooking can lead to a raw, beany odor. Cook until the soybeans have a slightly firm, crunchy texture.
Drain the cooked soybeans, but do not discard the cooking water; let it cool.
In a blender, add the cooked soybeans and cooled soybean cooking water gradually (a total of 8 cups), blending in 30-second intervals multiple times.
Add 1 tbsp of coarse sea salt to the blended soy milk broth and blend again for about 30 seconds to season.
Pour the blended soy milk broth through a fine mesh sieve or cheesecloth to strain out the pulp (비지, biji).
Cook your desired amount of traditional sōmen (소면) noodles in boiling water. After cooking, rinse them in cold water about 3 times and drain well.
Place the cooked sōmen (소면) noodles in a bowl, pour the original soy milk broth over them, and finish by garnishing with boiled egg, julienned cucumber, pine nuts, and ice.
💡 Tips
When cooking soybeans, avoid overcooking as it can result in a meju (메주)-like smell, and undercooking can cause a beany odor. It's best to cook them for about 5 minutes until they have a slightly firm, crunchy texture.
Do not discard the soybean cooking water; blending it with the soybeans will enhance the rich flavor.
Adjust and add salt to taste, as desired.
Kongguksu (콩국수) is best enjoyed cold, so add plenty of ice to serve it chilled and refreshing.
📦 Storage & Reuse
Once prepared, the soy milk broth can be stored in an airtight container in the refrigerator for 2-3 days, retaining its freshness.
It's best to consume it as soon as possible, as prolonged storage may cause the broth to separate or spoil.
Cooked sōmen (소면) noodles, after being thoroughly drained, can be individually wrapped and refrigerated for consumption the next day.
Leftover soy milk broth is also delicious as a dip for bread, mixed with rice, or warmed up like soymilk for a savory and hearty drink.
While you can freeze it to use later for kongguksu (콩국수), please note that the taste and consistency might change slightly upon thawing.
🥢 Who This Is For
This kongguksu (콩국수) is highly recommended when you want a cool and satisfying meal on a hot summer day.
It's especially great as a special treat when the heat makes you lose your appetite.
It's also a nutritious snack for children and excellent for boosting energy in the elderly.
For side dishes, the crisp texture of geotjeori (겉절이, fresh kimchi) or refreshing yeolmu kimchi (열무김치, young radish kimchi) will pair wonderfully with the savory kongguksu.
Serving it alongside bibim guksu (비빔국수, spicy mixed noodles) with gochujang (고추장) sauce will create a harmonious sweet, salty, and spicy balance, making for an even richer dining table.
