Why it works: Horse and radish work together. They rank in the top 4% of all ingredient pairs, and cooks put them together in 529 recipes. Both carry 2-methylbutyraldehyde, which smells malty, chocolate. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce and give it a rich, smooth body as they set with gentle heat.
- Anchovies
- Add a deep, savoury saltiness that rounds out the sauce.
- Vinegar
- Adds sharpness that balances the richness of the egg yolks.
- Horse-radish
- Contributes pungent heat and aroma that is mellowed by boiling.
The step that matters
Stirring the egg yolks over heat. Egg yolks thicken through gentle heat, but if the sauce gets too hot or is not stirred, the proteins can scramble and turn grainy. Stir constantly over low heat and keep the sauce below a simmer until it thickens.
