Cooking Instructions
Step 1
Wash the cucumber thoroughly, trim the ends, and thinly slice it into matchsticks. Slicing them not too thinly will help preserve a satisfying crunch.
Step 2
Peel the onion and slice it thinly into matchsticks. If you prefer a milder flavor, soak the sliced onions in cold water for about 5 minutes, then drain. This removes some of the sharpness, making them softer.
Step 3
In a bowl, combine 400ml of cold water with 1 Tbsp sugar, 0.5 Tbsp salt, 0.5 Tbsp minced garlic, 0.5 Tbsp coarse gochugaru, 3 Tbsp vinegar, 2 Tbsp tuna extract, and 1 Tbsp sesame oil. Stir well until the seasonings are dissolved to create a refreshing chilled broth. Taste and adjust the sourness, sweetness, or saltiness according to your preference.
Step 4
Fill a wide serving bowl generously with ice cubes. The ice will keep the soup refreshingly cold.
Step 5
Arrange the prepared sliced onions and cucumbers attractively over the ice. For added color, consider garnishing with thinly sliced red chili peppers or perilla leaves.
Step 6
Finally, gently pour the chilled broth over the cucumbers and onions. You can enjoy it immediately, or chill it further in the refrigerator for an even colder, more refreshing experience.
