Spicy Korean Cucumber Kimchi (Oi Muchim)

Ingredients

• 3 Persian cucumbers (or 1 English cucumber)
• 1 tsp salt
• 1 tbsp gochugaru (Korean chilli flakes, add more if you want it spicier!)
• 1 tbsp soy sauce
• 1 tbsp rice vinegar
• 1 tsp sesame oil
• 1 tsp sugar
• 1 clove garlic, minced
• 1 tsp toasted sesame seeds
• 1 spring onion, thinly sliced

Instructions

1. Smash and chop. Smash cucumbers lightly with the flat side of a heavy knife until they split, then cut into bite-sized pieces. Smashing creates jagged edges that help the dressing cling to the cucumber rather than sliding off.
2. Salt and purge. Toss the cucumbers with salt in a colander and let sit for 5 minutes. Gently squeeze out the excess water. This draws out moisture so your kimchi doesn't become watery once you add the dressing.
3. Make the paste. In a large bowl, mix the gochugaru, soy sauce, rice vinegar, sesame oil, sugar, and minced garlic. Stir until it forms a thick, fragrant paste.
4. Toss and serve. Add the purged cucumbers to the paste and toss vigorously until every piece is well coated. Top with toasted sesame seeds and sliced spring onion.

Notes

Critical insight: Eat this within a few hours of making it. Unlike traditional cabbage kimchi, cucumber kimchi doesn't improve with long fermentation—the cucumbers just get soggy and lose their refreshing crunch.

Substitutions: Persian or English cucumbers are mandatory; standard slicing cucumbers are too watery and have thick skins. If you don't have gochugaru, you can use standard chili flakes, but use half the amount as they are significantly spicier and lack the smoky sweetness of gochugaru.

Storage: Keeps in the fridge for up to 2 days in an airtight container, though the texture will soften by day two. Do not freeze.

Variations: Add thinly sliced white onion or julienned carrots for extra crunch and sweetness.

Pairs with: Serve alongside Butter Chicken or Miso Glazed Salmon to cut through the richness with bright, spicy acidity.
