Steps

Before you start

Have all ingredients at room temperature for smooth whisking
Use fresh limes or store-bought fresh lime juice—not bottled that contains preservatives
Taste as you build the dressing; shrimp paste intensity varies by brand

1
Bloom the shrimp paste
- In a small bowl, place the shrimp paste and warm water.
- Whisk vigorously for 1–2 minutes to dissolve and soften the paste, breaking up any lumps.
- The mixture will become pinkish and pasty.
- This step ensures the paste distributes evenly throughout the dressing without gritty bits.

Ready when: Paste is fully dissolved and smooth, no large clumps remain
Tip: If the paste remains very thick or grainy after whisking, pass it through a fine-mesh strainer to remove any sand or shell pieces, then return to the bowl.
2
Add lime and sugar
- Pour the fresh lime juice into the shrimp paste mixture and add the sugar.
- Whisk for 1 minute until the sugar dissolves completely.
- The dressing will become lighter in color and more fluid.
- Taste a small spoonful—you should detect both the brininess of the shrimp paste and the brightness of lime.

Ready when: Sugar is fully dissolved; dressing smells aromatic and pungent
Tip: Do not skip the tasting step—shrimp paste brands vary widely in intensity, so you may need to adjust the lime juice or sugar slightly.
3
Incorporate aromatics
- Add the minced garlic and chili to the bowl.
- Whisk for another minute to combine.
- The dressing will take on a vibrant pink-orange hue and will smell intensely aromatic—this is correct.

Ready when: Garlic and chili are evenly distributed; dressing is uniform in color
Tip: Finely mince the chili and garlic so they don't settle to the bottom of the bowl. You want each spoonful of dressing to have heat and flavor.
4
Finish with fish sauce
- Add the fish sauce to the bowl and whisk vigorously for 30 seconds to fully incorporate.
- The dressing is now complete.
- You should taste saltiness, sourness from lime, sweetness, heat, and a deep umami backbone.

Ready when: All ingredients are fully blended; no visible separation or streaks
Tip: Fish sauce adds saltiness, so taste before adding extra salt elsewhere in your dish. If the dressing tastes too intense, add another tablespoon of lime juice to balance.

Tips

Shrimp paste has a strong smell that many find off-putting at first—this is normal and expected. The aroma mellows once mixed with lime and the other ingredients.
This dressing is traditionally served with Vietnamese salads like green papaya salad (gỏi đủ đủ) or cabbage salad, and alongside grilled fish or shrimp.
For a milder version, reduce the shrimp paste to 2 tsp and remove the chili seeds before mincing. For extra heat, add a second chili.
Always mix the dressing just before serving for maximum aromatic impact and freshness.

Make ahead

Prepare the dressing up to 2 hours before serving. The flavors are brightest when mixed fresh, but it will hold in an airtight container at room temperature.

Storage & reheating

Room temperature: up to 2 hours. Refrigerator: up to 3 days in an airtight container (flavors will mellow). Do not freeze. Before serving after refrigeration, whisk again to recombine, and taste to adjust salt or lime if needed.

Substitutions

Thai bird's eye chilies, fresh → 1 tsp sambal oelek or chili paste. Sambal will make the dressing slightly thicker but will deliver similar heat and umami without the fresh texture.
palm sugar or light brown sugar → 1 tbsp honey or white granulated sugar. White sugar will work identically; honey adds a subtle floral note but is slightly wetter.
fresh lime juice → 3 tbsp rice vinegar or white vinegar. Vinegar is less bright but adds body; use 2 tbsp vinegar plus 1 tbsp lime juice if available for balance.
shrimp paste (mắm tôm) → 1½ tbsp anchovy paste plus 1 tsp miso. Anchovy paste and miso together mimic shrimp paste's umami, though the result is slightly less complex and pungent.
