📝 Editor's Notes
This recipe leverages the Cuna Soy Cafe machine to make Kongguksu (cold soybean noodle soup) easily and conveniently at home.
It's characterized by its richer and deeper flavor compared to regular Kongguksu, thanks to the use of Black Soybeans (흑미밤콩).
Its refreshing and light taste makes it an excellent special treat to beat the summer heat, and a great choice for those seeking a healthy meal.
With a relatively short cooking time of 44 minutes and no special skills required, even beginner cooks can confidently try this recipe.
It's a satisfying yet light meal.
🛒 Ingredient Tips
The Black Soybeans (흑미밤콩), the star of this Kongguksu, will add a unique flavor.
When choosing beans, it's important to select those with clean, glossy skins and no signs of insect damage.
Note that Korean-grown beans typically have uniform size and vibrant colors.
For the noodles, choose medium-thick noodles (중면) or Somyun (소면) that remain chewy after cooking.
Select fresh eggs to ensure the yolk is perfectly centered and to achieve a rich, non-fishy taste.
For cherry tomatoes, choose those with fresh stems, firm texture, and vibrant color.
Using seasonal ingredients will result in an even fresher and more delicious Kongguksu.
🔄 Substitution Guide
Instead of Black Soybeans (흑미밤콩), you can use regular White Soybeans (백태, mejukong) or Seoritae Black Soybeans (서리태).
Using white soybeans will result in a more familiar and lighter soybean broth, while Seoritae black soybeans offer a rich, savory flavor unique to black beans and a deeper color.
However, they might lack the unique flavor profile of black rice chestnut beans.
You can also use medium-thick noodles (중면) or Kalguksu (칼국수) noodles instead of Somyun (소면).
If you prefer to avoid wheat noodles, rice noodles or konjac noodles can be used for a lighter option.
For garnishes, you can substitute cherry tomatoes with cucumber slices, more boiled eggs, or sautéed zucchini strips to suit your taste.
Cucumber adds a refreshing crunch and cool taste.
🥘 Ingredients
👨🍳 Cooking Points
The most crucial cooking point in this recipe is making the soybean broth.
While the Cuna Soy Cafe makes it convenient, since the beans are used without pre-soaking, it's important to use the 'Kongguksu' mode correctly to avoid any raw bean flavor.
If you choose to soak the beans before use, you should reduce the water by about 100-150ml from 2.5 cups (600ml) to create a richer and more savory broth.
The second point is boiling the Somyun (소면) noodles: cook them in boiling water for about 3-4 minutes, then rinse them several times in cold water to completely remove starch and maintain a chewy texture without becoming soggy.
Finally, it's best to prepare the soybean broth in advance and chill it thoroughly in the refrigerator.
Serving with cold broth and even ice cubes floating on top will make for an even more refreshing and delicious Kongguksu.
👨🍳 Directions
First, boil the eggs and set aside.
Rinse 1.4 oz (40g) of Black Soybeans (흑미밤콩) thoroughly, then place them into the Cuna Soy Cafe machine with 2.5 cups (600ml) of water.
Select the 'Kongguksu' mode on the Cuna Soy Cafe and press the start button to make the soybean broth.
Boil 2.8 oz (80g) of Somyun Noodles (소면) in boiling water.
After cooking, rinse the somyun noodles several times in ice water, then drain completely in a colander.
Cut the boiled eggs and cherry tomatoes into bite-sized pieces and prepare them as garnishes.
Place the cooked somyun noodles in a bowl and pour the prepared soybean broth over them.
Arrange the prepared egg and cherry tomato garnishes on top of the noodles.
Serve chilled with ice cubes floating on top, if desired, and season with salt or sugar to taste.
Prepare some Kimchi (김치) on the side to enjoy with your meal.
💡 Tips
For an even colder and more refreshing taste, prepare the soybean broth in advance and chill it in the refrigerator.
You can use cherry tomatoes instead of cucumber, or use other vegetable garnishes according to your preference.
Adjust the seasoning with coarse salt (꽃소금) or sugar to your liking for a delicious taste.
If you soak the soybeans before using them, reduce the amount of water to make an even richer and more savory soybean broth.
📦 Storage & Reuse
The prepared soybean broth can be stored in an airtight container in the refrigerator for up to 2-3 days while remaining fresh.
It's a good idea to stir it well once more before serving.
While Somyun (소면) noodles are best eaten immediately after cooking, if you have leftovers, drain them completely, store them in an airtight container in the refrigerator, and briefly blanch them in hot water before eating to prevent them from becoming soggy.
Store garnishes like boiled eggs and cherry tomatoes separately and add them right before serving.
Leftover soybean broth can also be used as a dip for bread or blended into a smoothie for a nutritious snack.
🥢 Who This Is For
This Kongguksu is highly recommended for those looking for a cool and healthy meal during the hot summer months.
It's also excellent for individuals on a diet or those who prefer lighter meals.
While Kongguksu is filling on its own, pairing it with Kimchi (김치) will enhance the flavors even more.
Chilled Radish Kimchi (열무김치) or fresh, crunchy Kimchi (겉절이) pair exceptionally well.
It's a perfect dish for the whole family to enjoy and suitable for entertaining guests.
It would also make a wonderful choice for dinner or a weekend brunch.
