Why it works: Horseradish and tarragon share more aroma than cooks usually use. They rank in the top 4% of all ingredient pairs, and cooks put them together in 73 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Horseradish Sauce
Ingredients
Directions
Make the sauce
Grate the horseradish root finely until you have 1 cup.
Simmer the grated horseradish in 2 cups of broth.
Once done, thicken the broth over low heat with 2 beaten egg yolks and 2 teaspoons of tarragon vinegar.
Add 1 teaspoon of Buckle's horseradish zest, 1 teaspoon of pepper, ¼ teaspoon of coarse sea salt, and a pinch of grated nutmeg.
Serve
Serve in a sauceboat.
For a richer sauce, mix in 1 cup of Bechamel off the heat, then heat gently in a bain-marie until hot but not boiling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Horseradish root
- Provides the sharp, pungent flavour that defines the sauce.
- Broth
- Forms the liquid base that carries the horseradish flavour.
- Egg yolks
- Thicken the broth as they gently set over low heat, giving the sauce body.
- Tarragon vinegar
- Adds acidity that brightens the sauce and balances its richness.
- Bechamel sauce
- Adds creaminess and body when mixed in for a richer finish.
The step that matters
Thickening the egg yolks over low heat. Egg yolks set at moderate temperatures, and high heat or boiling can scramble them into lumps. Gentle heat and constant stirring keep the sauce smooth and thickened.
Swap the nutmeg
