- 1/2 cup cucumber thinly sliced or diced (Persian or English cucumbers work best; peel if using regular cucumbers)
- 1/4 cup red shallots thinly sliced (can substitute with red onion if needed)
- 1 or 2 Thai hot chilies finely chopped (adjust to taste; use gloves if sensitive)
- 2 tablespoons coriander cilantro leaves, roughly chopped
- 1/3 cup distilled white vinegar
- 2 tablespoons sugar
- 1 teaspoon salt
Prepare the vegetables
Start by slicing the cucumber into thin half-moons or small dice for a more delicate texture. Thinly slice the shallots and finely chop the chilies. Roughly chop the cilantro leaves.
Tip: To keep cucumbers crisp, chill them in the fridge before cutting.
Make the sweet-sour dressing
In a small mixing bowl, combine the distilled white vinegar, sugar, and salt. Stir until the sugar and salt are fully dissolved.
Tip: Warming the vinegar slightly can help dissolve the sugar faster, but room temperature is fine too.
Combine all ingredients
In a serving bowl, mix together the cucumbers, shallots, chilies, and cilantro. Pour the vinegar dressing over the vegetables and toss gently to combine.
Tip: Let the relish sit for 10–15 minutes to allow the flavors to meld before serving.
Adjust and serve
Taste and adjust the seasoning if needed. Add more sugar for sweetness, vinegar for tang, or an extra chili if you like it spicier.
Tip: Serve chilled or at room temperature for the best flavor.
No cilantro? Substitute with fresh mint or Thai basil for a different herbal note.
Low-sugar alternative: Use a sugar substitute like stevia or monk fruit sweetener.
Mild version: Remove the seeds from the chilies or use less spicy peppers.
Make ahead: Prepare the dressing in advance and mix in the vegetables just before serving.
Common mistake: Don’t skip dissolving the sugar and salt properly—it ensures a balanced flavor.
