How to Make Oi Muchim: Korean Cucumber Salad

Ingredients:

1 cucumber
1/4 onion (25 g / 0.9 ounces)
1 Tbsp Korean coarse salt (or rock salt) *** or 1 tsp fine sea salt
1 Tbsp gochugaru (Korean chili flakes)
1 tsp white vinegar (or rice vinegar)
1 tsp white sugar
1 tsp minced garlic
1 tsp toasted sesame seeds
1/2 tsp gochujang (Korean chili paste, optional)
A smidgen sesame oil (about 1/32 teaspoon, optional)

Directions:

Rinse the cucumber thoroughly under cold running water. Trim off both ends and thinly slice the cucumber into approximately 0.5 cm (0.2 inches) pieces.
Place the cucumber slices in a large mixing bowl. Add the salt and gently mix them together. (Coarse salt is recommended, but if you’re using fine salt, sprinkle it evenly to avoid overly salty patches.) Let it sit for 15 minutes.
While waiting, thinly slice the onion. Prepare the seasoning sauce by mixing all the remaining ingredients together.
After 15 minutes, rinse the cucumber under cold running water to remove any remaining salt. Drain the water using a strainer and pat the cucumber slices lightly dry with kitchen paper. Place them in a clean, dry mixing bowl.
Add the sliced onion and seasoning sauce. Mix everything lightly but thoroughly with your hands. You might want to wear food prep gloves for this step as you need to coat the cucumber well with the sauce.
Place the seasoned cucumber in a sealed glass container and refrigerate for 30 minutes to chill. Then serve with a bowl of rice and other Korean side dishes. Enjoy!
