Ingredients List
🥒 Main Ingredients:
- 4 small cucumbers (Persian or Kirby work best)
- 1 tbsp coarse sea salt (for salting)
- 1 small carrot, julienned
- 2 green onions, sliced
- 1 clove garlic, minced
- 1 tsp grated ginger
🌶️ For the Kimchi Paste:
- 1 ½ tbsp Korean red pepper flakes (gochugaru)
- 1 tbsp fish sauce (or soy sauce for vegetarian)
- 1 tsp sugar
- 1 tbsp rice vinegar or apple cider vinegar
- 1 tbsp sesame oil
- ½ tsp sesame seeds (for garnish)
Timing
- Preparation Time: 15 minutes
- Salting Time: 30 minutes
- Fermentation: 4–6 hours (optional for stronger flavor)
- Total Time: ~45 minutes (ready to eat same day)
Step-by-Step Instructions
Step 1: Salt the Cucumbers
Slice cucumbers into thick rounds or quarters lengthwise. Toss them with sea salt and let sit for 30 minutes to draw out moisture. Rinse lightly and pat dry.
Step 2: Make the Kimchi Paste
In a bowl, mix gochugaru, fish sauce, sugar, vinegar, garlic, ginger, and sesame oil until a thick paste forms.
Step 3: Add Vegetables
Combine cucumbers, carrots, and green onions in a mixing bowl. Add the kimchi paste and toss gently with your hands (use gloves!) until evenly coated.
Step 4: Store and Ferment
Transfer to a clean glass jar or airtight container. Leave at room temperature for 4–6 hours to start fermentation, or refrigerate immediately for a milder flavor.
Step 5: Serve
Garnish with sesame seeds and serve chilled as a side dish, salad, or topping for rice, noodles, or grilled meats.

- Use as a spicy salad topping for freshness and crunch.

Common Mistakes to Avoid
- Skipping the salting step: This ensures crisp texture and prevents sogginess.
- Over-salting: Rinse cucumbers well to balance flavor.
- Too much vinegar: It can overpower the spice — balance is key.
- Fermenting too long: Cucumbers ferment faster than cabbage; don’t leave at room temperature more than 12 hours.
Storing Tips
- Refrigerator: Store in an airtight jar for up to 1 week (best eaten within 3–4 days for freshness).
- Fermentation Note: The flavor deepens over time, but cucumbers will soften slightly.
- Freezer: Not recommended — texture changes when thawed.
