Why it works: Mustard and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 901 recipes. Both carry methyleugenol, which smells clove, spice. The science ↓

Ingredients
Directions
Make the base
Beat the egg yolks in a bowl and strain them.
Gradually mix in the pepper, salt, oil, vinegar, and mustard.
Finish and chill
Add equal parts of cream and calves'-foot jelly if using 4 tablespoons of oil.
Set the mixture on ice until needed.
Variations
For a custard variation, combine 4 eggs, ½ cup milk, and gelatine, then cool.
Add ½ cup cream and gradually mix in 1½ tablespoons of salad oil and tarragon vinegar with salt to taste.
For a thicker sauce, slowly add oil and vinegar while stirring until it reaches a thick cream consistency.
Season with salt and white pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Lecithin in the yolks helps hold the oil and vinegar together as a stable emulsion.
- Salad oil
- Forms the fat phase that gives the sauce its rich body and thickness.
- Vinegar
- Adds acidity that sharpens the flavor and balances the richness of the oil.
- Mustard
- Its natural emulsifiers help keep the oil dispersed and the sauce from separating.
- Cream
- Adds moisture and softness, mellowing the sauce and adding richness.
- Gelatine
- Sets and firms the custard variation as it cools.
The step that matters
Adding the oil. Oil must be added slowly while whisking so it breaks into tiny droplets that the yolk can coat. Adding it too fast can overwhelm the yolk, and the emulsion will split into a greasy, separated sauce.
Swap the mustard

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