3. Slice and Salt the Cucumbers
♡ The step that keeps Oi Muchim crunchy
Slice the cucumbers into thin rounds or diagonal pieces, then sprinkle them with salt and let them sit for about 10 minutes. This helps pull out extra moisture so your cucumber salad stays crunchy instead of becoming watery. After salting, gently squeeze out the liquid and pat the cucumbers dry. This step is simple, but it makes a huge difference in the final texture.

4. Make the Spicy Seasoning
♡ Sweet, spicy, tangy, and nutty
In a bowl, mix gochugaru, minced garlic, sesame oil, vinegar, sugar, and sesame seeds. The flavor should be spicy, slightly sweet, tangy, and nutty. If you like it spicier, add more gochugaru. If you like it brighter, add a little more vinegar. If you want it softer and more balanced, add a tiny bit more sugar. This is an easy recipe to adjust to your taste.

5. Mix Everything Together
♡ Toss gently so the cucumbers stay crisp
Add the drained cucumbers to the seasoning and gently toss until every piece is coated. You do not need to overmix it. The cucumbers should look glossy and lightly covered in red seasoning, not soaked in sauce. Taste one piece and adjust with a little more vinegar, sesame oil, or gochugaru if needed. Once mixed, your Oi Muchim is ready to eat.
