Step-by-Step Instructions
- Prepare the cucumbers: Wash the cucumbers thoroughly. If using regular cucumbers, peel them, as the skin can be too bitter. For Korean cucumbers, you may leave the skin on for added texture.
- Slice the cucumbers: Cut the cucumbers in half lengthwise, then slice them into thin half-moons or quarter-moons, depending on your preference.
- Salt the cucumbers: In a mixing bowl, sprinkle the sliced cucumbers with salt. Let them sit for about 15-20 minutes. This will help draw out excess moisture and enhance the flavor.
- Prepare the broth: In a large bowl or pot, mix together the water, vinegar, sugar, sesame oil, minced garlic, and chili flakes. Stir well until the sugar dissolves completely.
- Combine cucumbers and broth: After the cucumbers have released some water, drain them and add them to the broth mixture. Stir gently to combine.
- Chill: Refrigerate the soup for at least 30 minutes, allowing the flavors to meld and the soup to chill thoroughly.
- Serve: Ladle the Oi Naengguk into bowls. Garnish with sesame seeds and chopped chives or scallions, if desired. Enjoy this refreshing dish cold.
