Why it works: Thyme and basil match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,768 recipes. Both carry terpineol, which smells pine, woody. The science ↓

Directions
Make the sauce base
Slice the onions and fry them in oil until they begin to color.
Transfer the onions to a saucepan with white wine, broth, lemon slices, garlic, bay leaf, thyme, basil, and cloves.
Boil for 15 minutes, then strain the mixture.
Finish the sauce
Add capers, chopped anchovy, pepper, salt, and horseradish.
Warm the sauce gently without boiling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Fried until coloured, they build a sweet, savoury base for the sauce.
- White wine
- Adds acidity and aroma that brighten the boiled base.
- Horseradish
- Provides the sharp, pungent heat that defines the sauce.
- Capers
- Add a briny, sharp acidity that balances the richness of the sauce.
- Anchovy
- Contributes deep savoury flavour that melts into the sauce.
The step that matters
Warm the sauce gently without boiling. Horseradish loses much of its pungency when heated for long or at high heat, and boiling can also cause the sauce to separate or taste harsh. Gentle warming keeps the flavour bright and the texture smooth.
