Ingredients
- For the Salad:
- 2 English cucumbers or 5–6 Persian cucumbers sliced into thin rounds (about ¼-inch thick).
- 1 teaspoon salt – for drawing out excess moisture.
- 2 green onions finely chopped.
- For the Dressing Oi Muchim Sauce:
- 1 tablespoon soy sauce – adds umami depth.
- 1 tablespoon rice vinegar – for brightness and tang.
- 1 tablespoon gochugaru Korean red pepper flakes – adjust to your spice comfort.
- 1 teaspoon sugar – balances the heat and acidity.
- 1 teaspoon minced garlic – fresh is best for that punchy flavor.
- 1 teaspoon toasted sesame oil – gives it that nutty aromatic finish.
- 1 teaspoon sesame seeds black or white – for garnish and crunch.
Instructions
- Slice the Cucumbers
- Slice the cucumbers into thin, even rounds — about ¼-inch thick. You can use a sharp knife or mandoline for consistency. The thinner the slices, the more flavor they’ll absorb.
- Salt the Cucumbers
- Transfer the slices to a bowl and sprinkle with 1 teaspoon of salt. Toss gently and let sit for 10 minutes. This draws out excess moisture and keeps the salad crisp.
- After resting, gently squeeze the cucumbers to remove water. Don’t skip this — it’s key for that crunchy texture!
- Make the Dressing
- In a separate bowl, combine soy sauce, rice vinegar, gochugaru, sugar, minced garlic, and toasted sesame oil. Whisk until the sugar dissolves and everything’s well mixed.
- Combine and Toss
- Add the drained cucumbers and chopped green onions to the dressing. Toss gently until the cucumbers are evenly coated with the spicy, glossy sauce.
- At this stage, your kitchen will start to smell amazing — the nutty sesame oil and garlic are irresistible.
- Garnish and Serve
- Sprinkle sesame seeds over the top before serving. You can also add a few black sesame seeds for color contrast.
Notes
- Don’t skip salting. If you skip this step, your salad will become watery within minutes.
- Use the right cucumbers. English or Persian cucumbers work best; avoid standard waxy cucumbers, which can taste bitter and watery.
- Balance your heat. Gochugaru adds smoky, fruity spice — start with less if you’re sensitive to heat.
- Serve cold. This salad tastes best chilled, especially alongside warm dishes like Korean BBQ.
- Make small batches. Oi muchim is best fresh — the cucumbers lose their crunch after 24–36 hours.
