Ingredients
- 2-3 Thai chilies – These are essential for that signature heat. Adjust the quantity to your spice preference; more chilies equal more kick!
- 1 clove garlic (optional) – Adds a pungent depth to the flavor. If you prefer it milder, feel free to skip it.
- 1/4 cup white vinegar – Use a good quality vinegar for the best results. Avoid substitutes like apple cider vinegar as they can alter the taste.
Additional Notes
- Freshness: Be sure to pick fresh chilies that are bright and firm.

Optional Step: Char the chilies and garlic (if using) in a dry skillet over high heat until they are lightly charred, about 2-3 minutes. This step intensifies the flavors and adds a smoky touch.
Pound to Paste: If you’ve opted for garlic, pound the chilies and garlic together into a paste using a mortar and pestle. This will allow the flavors and oils to release beautifully.
Mix with Vinegar: Transfer the chili paste into a bowl, and add the white vinegar. Stir well to combine, ensuring there are no lumps.
Blender Option: For a smoother consistency, you can blend all ingredients together in a blender. This is also useful if you’re doubling the batch!
