Hong Shin-ae's Oi Sobagi

A crisp, rice-stealing summer kimchi that stays crunchy without turning mushy, using the secret boiling salt water shower method.

🙋 Recommended for

  • For those who have failed at making oi sobagi because the cucumbers always turned mushy quickly.
  • For those who want to learn a refreshing, crunchy, golden-ratio kimchi that will stimulate your appetite in summer.

Ingredients needed 🛒3 servings

  • 3 white cucumbers
  • a handful of small green onions (or chives)
  • 3–4 tbsp gochugaru
  • 3 tbsp sand lance fish sauce
  • 2 tbsp minced garlic
  • 1/2 tbsp minced ginger
  • a little plum syrup
  • coarse salt, as needed
  • 1.5L water

Recipe 🍳

  1. Wash the cucumbers clean, cut them into bite-sized pieces (half the length of regular sobagi), and make a cross-shaped (+) cut leaving 1 cm at the bottom.
  2. Add 1 tbsp coarse salt to 1.5L water and bring to a rolling boil.
  3. Place the cucumbers on a tray, pour the boiling salt water evenly over them to shower them, then let them cool naturally without rinsing in cold water.
  4. Cut the small green onions into finger-length pieces.
  5. In a bowl, combine 2 tbsp minced garlic and 1/2 tbsp minced ginger (4:1 ratio), mix in the fish sauce, gochugaru, and plum syrup, then add the chopped green onions to make the stuffing.
  6. Once the cucumbers are completely cooled, apply a very small amount of coarse salt evenly into the cross-shaped cuts.
  7. Stuff the seasoning mixture tightly into the cuts, leaving no gaps.
  8. Place the oi sobagi neatly in a container, let it ferment at room temperature for about a day, then store in the refrigerator and serve chilled.
  1. Cut the cucumbers and make cuts, then pour boiling salt water over them and let cool for a crisp texture.
  2. Mix garlic, ginger, fish sauce, gochugaru, and plum syrup with green onions to make the kimchi stuffing.
  3. Lightly salt the cuts, then fill thoroughly with the seasoning mixture to finish.

Cooking tips 💡

  • Instead of boiling cucumbers in salt water, simply pouring hot water over the surface ensures the seeds inside don't become mushy and the texture stays crisp for a long time.
  • Adding too much salt directly to the seasoning can draw out water from the vegetables and make them mushy, so the secret is to apply a small amount of salt directly inside the cucumbers.
  • If you plan to eat the oi sobagi right after making it, be sure to add plum syrup to enhance sweetness and aid fermentation—it's key to the flavor.
