๐ฉโ๐ณ How to Make Oi Muchim
1๏ธโฃ Prepare the Cucumbers
Wash cucumbers thoroughly by rubbing them lightly with salt. Peel slightly, leaving some skin for texture. Slice into bite-sized pieces, about 0.5 cm thick.
2๏ธโฃ Salt the Cucumbers
Add 1 tablespoon coarse salt to the sliced cucumbers. Let them sit for about 10 minutes. This draws out excess moisture and improves crunch.
3๏ธโฃ Slice the Onion
While cucumbers are salting, thinly slice the onion.
4๏ธโฃ Rinse and Drain
After 10 minutes, rinse cucumbers under cold water. Drain thoroughly using a colander and gently squeeze out excess water.
5๏ธโฃ Make the Sauce
In a bowl, mix gochugaru, sugar, maesil syrup, soy sauce, minced garlic, vinegar, and sesame seeds until well combined.
6๏ธโฃ Mix Everything Together
In a large mixing bowl, combine cucumbers, onion, and seasoning sauce. Toss gently to coat evenly. Avoid over-mixing to maintain crisp texture.
Serve immediately for the best crunch.
๐ก Tips for the Best Korean Cucumber Salad
- Light peeling keeps texture crisp while preventing bitterness.
- Adjust vinegar and sugar to balance sweetness and acidity.
- Add a drizzle of sesame oil for a richer finish if desired.
- Best eaten fresh; prolonged storage softens the cucumbers.
๐ง Storage
Store in the refrigerator for up to 1 day. Drain excess liquid before serving again.
โ FAQ
Can I use gochujang instead of gochugaru?
Yes, but the texture and sweetness will change. Gochujang creates a thicker, richer sauce.
Why do we salt cucumbers first?
Salting removes excess moisture, enhances crunch, and prevents the salad from becoming watery.
Can I skip maesil syrup?
Yes. Substitute with additional sugar or a small amount of honey.
Is this dish spicy?
It has mild to moderate heat depending on the gochugaru used. Adjust to preference.
