Why it works: Tarragon and horseradish 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 ↓
Whisked Mayonnaise
Ingredients
Directions
In a copper basin or bowl, combine melted jelly, mayonnaise, tarragon vinegar, and horseradish.
Place the bowl on ice and whisk gently until frothy.
Stop whisking as soon as the sauce begins to solidify; it should remain almost fluid for mixing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Melted jelly
- Sets as it cools, giving the sauce body and a light, firm structure.
- Mayonnaise
- Adds fat and emulsified richness, giving the sauce a smooth, creamy texture.
- Tarragon vinegar
- Adds acidity and sharp aroma that cut through the richness of the fat.
- Horseradish
- Contributes pungent heat and aroma to the sauce.
The step that matters
Stop whisking as soon as the sauce begins to solidify. The jelly sets as it cools, so overwhipping past the first signs of setting can make the sauce stiff and grainy instead of light and fluid for mixing. Whisk gently and stop early to keep it airy and spreadable.

Fit is the average pairing score against tarragon, vinegar. Candidates are from the same food group and used in at least 100 recipes.
