XO Sauce in the kitchen

A Hong Kong-style luxury chilli sauce with dried seafood, ham, garlic and chilli. Use sparingly for huge savoury depth.

Why make it

Make xo sauce when you want a reliable sauce that adds contrast, moisture and a clear flavour direction to everyday meals.

Best with

fried rice, noodles, scallops, eggs, greens

Method

Step-by-step

  1. Step 1

    Prepare the ingredients for XO Sauce: 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 XO Sauce 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 XO Sauce 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.
