Oi Muchim is a quick, crisp side dish made by salting cucumbers to draw out excess moisture and tossing them in a punchy mixture of red chili flakes, garlic, and vinegar. The result should be snappy and bright, served immediately to maintain the crunch.

Ingredients

  • 2 Kirby or Persian cucumbers, sliced into 1/8-inch rounds
  • 1 tsp sea salt
  • 1.5 tbsp gochugaru (Korean red chili flakes)
  • 1 tbsp rice vinegar
  • 1 tsp fish sauce
  • 1 tsp sugar
  • 1 clove garlic, minced
  • 1 green onion, finely chopped
  • 1 tsp toasted sesame seeds

Step by step

  1. Prep the cucumbers

    Slice the cucumbers into uniform rounds. Toss with salt in a colander and set over a bowl for 10 minutes.

  2. Dry

    Rinse the salt off the cucumbers and use a clean kitchen towel or paper towels to pat them bone-dry.

  3. Make the dressing

    In the large mixing bowl, combine the gochugaru, rice vinegar, fish sauce, sugar, garlic, and green onion. Whisk with a fork until the sugar dissolves.

  4. Combine

    Add the cucumbers to the bowl. Use your hands or a pair of tongs to gently toss until every slice is coated in a deep red glaze. Sprinkle with sesame seeds and serve.

Questions people ask

Can I make this ahead of time?

It is best eaten within an hour of assembly. If left in the fridge, the cucumbers will continue to release water and become soggy.

What if I don't have fish sauce?

A light soy sauce is a functional substitute, though it lacks the depth of the fermented fish sauce.

Tips

  • Use Kirbys or Persians; their thin skins and small seeds are essential for keeping the texture crisp.
  • Don't let the cucumbers sit in the salt for more than 15 minutes, or they will begin to lose their structural integrity.
  • If you want more heat, add an extra half-tablespoon of chili flakes, but do it gradually.

Variations

  • Allium heavy: Add half of a small yellow onion, sliced into paper-thin strips, for extra sharp bite.
  • Sesame oil finish: Add half a teaspoon of toasted sesame oil at the very last second for a nutty finish.
