Nuoc Cham in the kitchen

A Vietnamese dipping sauce of fish sauce, lime, sugar, garlic and chilli. It should balance sweet, salty, sour and heat.

spring rolls, noodle salads, grilled pork, rice bowls

Method

Step-by-step

  1. Step 1

    Prepare the ingredients for Nuoc Cham: chop aromatics finely, measure liquids and keep cold emulsions cold or warm sauces gently warm before combining.

    Look for: Everything is measured and ready before mixing. Tip: Taste the strongest ingredient first so you know how much balance it needs. Avoid: Starting without prep can make emulsions split or reductions catch.

  2. Step 2

    Make the Nuoc Cham by whisking, blending, simmering or reducing as appropriate. Add liquids gradually and stop when the sauce is cohesive and the right thickness for spooning, dipping or drizzling.

    Look for: The sauce looks cohesive and clings lightly to a spoon. Tip: For cold sauces, rest for 10 minutes so garlic, herbs and acid settle. Avoid: Boiling delicate creamy or egg-based sauces can split them.

  3. Step 3

    Taste the Nuoc Cham and adjust salt, acid, sweetness and heat. Serve immediately or chill in a covered container until needed.

    Look for: The final flavour tastes slightly bold on its own, because food will soften it. Tip: A final squeeze of lemon, vinegar or tiny pinch of salt often wakes up the whole sauce. Avoid: Under-seasoned sauce disappears once it is served with food.
Storage

Make ahead and storage

Storage

Store covered in the fridge for 2–4 days depending on freshness of dairy, herbs or eggs. Reheat cooked sauces gently and discard anything sour, fizzy or stale.

Make ahead

Make ahead where useful, then adjust salt, acid and thickness just before serving because chilling can dull flavour and thicken the texture.

Freezing

Most fresh sauces do not freeze perfectly, especially emulsions and dairy sauces. Cooked gravies, reductions and fruit sauces freeze better.
