Tools Needed
- Pot
- Spoon
- Knife
- Cutting board
Ingredients
- Cucumber: 1 kg
- Chili pepper (non-spicy): 1
- Chili pepper: 3
- Garlic: 1 meter
- Spices
- Fish sauce
- Sugar: 80g + 100g
- Water: 100ml
Step-by-Step Instructions
Step 1. Prepare the Cucumbers
- Wash cucumbers thoroughly and use the skin. Choose firm cucumbers of the right size. Cut off both ends, then cut the cucumber in half and remove the seeds.
- Scrape the inside of the cucumber with a spoon to remove excess water. Cut the cucumber diagonally into approximately 2cm pieces.


Step 2. Initial Marinating
- Slice the chili pepper and garlic. Chop the remaining garlic and chili peppers.
- In a bowl, mix 80g of sugar (or salt), sliced garlic, and chopped chilies with the cucumbers. Let it sit for 2 hours to release water and soften.
- After 2 hours, mix the cucumber well to distribute the water evenly. The cucumbers should be a bit chewy.



Step 3. Make the Fish Sauce Mixture
- In a thick pot, caramelize 2 tablespoons of sugar over low heat, shaking constantly to prevent burning. Add 100ml of water, 100ml of fish sauce, and the remaining 100g sugar. Stir until the sugar is dissolved.

Step 4. Final Marinating and Chilling
- Add the garlic and chili to the fish sauce mixture once it has cooled completely. Add the cucumbers and let it soak for at least 5 hours, or overnight for a darker color and richer flavor.
- After 5 hours (or overnight), the cucumbers will be soft, colored, and infused with spices. Refrigerate to preserve crispness.

Tips
- Use firm, appropriately sized cucumbers for best results. Removing the seeds helps prevent excessive water release.
- If using salt instead of sugar, wash and squeeze the cucumbers to remove excess salt after soaking.
- Let the fish sauce mixture cool completely before adding the cucumbers; warm fish sauce may make the cucumbers mushy.
- For a richer color and flavor, let the cucumbers soak for 1-2 additional days at room temperature before refrigerating.

Absolutely! Start with a smaller amount of chili, and taste as you go. You can always add more, but you can't take it away!
