How to Make Korean Cold Cucumber Soup (Oi Naengguk)

  1. Slice the cucumbers into thin round slices. Salt them and leave them for 10-15 minutes to let them release their juice.
  2. In a large bowl, mix together the vinegar, sugar, soy sauce, sesame oil, and minced garlic. This will be your marinade.
  3. Add the chopped green onions and ground red pepper to the marinade. If you don't like spicy, you can skip the red pepper.
  4. Squeeze the cucumbers to remove excess juice and add them to the marinade. Stir well to ensure the cucumbers are evenly coated with the marinade.
  5. Add the cold water and stir. If you want, add ice for extra coolness.
  6. Before serving, sprinkle the soup with sesame seeds.

Enjoy your meal! This soup is perfect for a hot summer day.
