Ingredients

- 4 tablespoons Fish sauce (Nam Pla) (Core salty‑umami base; choose a brand you like)
- 1 tablespoon Rice vinegar (or white vinegar) (Adds bright acidity)
- 3 tablespoons Fresh lime juice (Adjust to taste; start with 2 tbsp then add more if needed)
- 4 cloves Garlic cloves (Handful, roughly peeled)
- 4 chilies Red Thai chilies (Adjust quantity for heat; medium‑spicy level used in video)
- 2 chilies Green Thai chilies (Adds fresh heat and color)
- 1 inch Coriander root (cilantro root) (Trimmed, roughly chopped; discard tough ends)
- 2 tablespoons Fresh coriander leaves (cilantro) (Roughly chopped; adds herbaceous freshness)
Instructions
Measure liquid and sweet components
Place the white sugar, palm sugar, fish sauce, rice vinegar and 2 tablespoons of fresh lime juice into a small bowl.
Time: PT2M
Dissolve the sugars
Continue stirring the mixture over low heat on the stovetop for about 1‑2 minutes, or simply keep stirring until the palm sugar is fully melted and the liquid looks uniform.
Time: PT3M
Temperature: low heat
Prep aromatics
Peel the garlic cloves and roughly chop them. Trim the coriander root, discard any woody ends, and roughly chop. Slice the red and green chilies (keep seeds if you want extra heat). Roughly chop the coriander leaves.
Time: PT5M
Blend the sauce
Add the dissolved sweet‑salty base and all prepared aromatics into the blender. Blend on high for 10‑15 seconds, or until the sauce is smooth but still slightly textured.
Time: PT2M
Taste and balance
Taste the sauce. If it needs more sourness, add the remaining 1 tablespoon of lime juice. If it’s not salty enough, add a little more fish sauce (½ tsp at a time). Stir well.
Time: PT1M
Rest the sauce
Transfer the sauce to a clean jar, seal, and let it sit for at least 5 minutes to allow the flavors to meld.
Time: PT5M

Critical Steps — Do Not Skip
- Fully melt the palm sugar into the fish‑sauce mixture; unmelted sugar gives a grainy texture.
- Blend all aromatics until smooth; under‑blending leaves large pieces of garlic or chili that can dominate the flavor.
Chef Tips from the Video
- Use a high‑quality fish sauce; it makes a huge difference in depth of flavor.
- Fresh lime juice beats bottled for brightness.
- If you don’t have coriander root, use the tender stems of cilantro; they provide a similar earthy note.
Troubleshooting
Sauce is too salty.
Add a little more lime juice or a pinch of sugar, then stir and taste again.
Sauce is grainy.
Blend longer or pass the sauce through a fine sieve; ensure the palm sugar was fully melted before blending.
Sauce is too thick.
Thin with a splash of water or extra vinegar/lime juice, a teaspoon at a time.
Storage
Refrigerator: Up to 2 weeks in an airtight jar.
Freezer: Up to 1 month; thaw in the refrigerator before use.
Room temperature: Not recommended; may spoil after a few hours.
Make-Ahead Tips
- Make the sauce a day ahead; it tastes even better after the flavors marry.
- Double the batch and freeze portions in ice‑cube trays for quick single‑serve portions.
