Why it works: Shallot and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 859 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Reading Sauce
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the sauce
Combine walnut pickle and cold water in a large bowl.
Add soy sauce, shallots, bruised ginger, capsicums, mustard seed, cayenne pepper, bay leaves, and essence of anchovy, then mix well.
Let sit for at least 24 hours to allow flavors to meld.
Finish
Strain before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnut pickle
- Provides the dark, concentrated base flavor that the sauce is built around.
- Soy sauce
- Adds salty, savory depth and umami to the liquid base.
- Shallots
- Contribute mild onion-like sharpness that mellows during resting.
- Whole ginger
- Releases aromatic, slightly spicy notes into the liquid as it steeps.
- Mustard seed
- Adds a sharp, pungent bite that carries through the sauce.
- Essence of anchovy
- Boosts savory, umami depth without a distinct fishy taste.
The step that matters
Letting the sauce sit for at least 24 hours. Flavors from aromatics and seasonings need time to extract and blend into the liquid. Straining too early leaves the sauce harsh and unbalanced, with the raw edges of shallots, ginger and mustard seed dominating.
Swap the ginger
How well each one fits the dish's main ingredients (walnut, sauce, shallot, capsicum, mustard, pepper, anchovy):
