Why it works: Tarragon and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 602 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Vinaigrette Sauce
Ingredients
Directions
Make the dressing
In a bowl, mix the salad oil and tarragon vinegar well.
Add the chopped gherkin, parsley, and shallot.
Season with salt and pepper.
Make the sauce
In a separate bowl, combine the butter, cream, egg yolks, tarragon vinegar, pepper, salt, and mustard.
Place the bowl over a pan of boiling water and beat the mixture until it thickens and becomes creamy. Be careful to prevent curdling.
If it curdles, add 2 more egg yolks.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the mixture and thicken it as they heat, giving a creamy body.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the sauce.
- Cream
- Adds moisture and softness, mellowing the sharpness of the vinegar.
- Salad oil
- Provides the fat base that carries the flavors of the dressing.
- Tarragon vinegar
- Adds acidity and a sharp herbal note that brightens the sauce.
- Mustard
- Helps stabilize the emulsion and adds a sharp, savory bite.
The step that matters
Beat over gently simmering water and watch for curdling. Egg yolks thicken as their proteins set with gentle heat. If the bowl gets too hot or the mixture overheats, the yolks scramble and the sauce curdles instead of becoming smooth and creamy.
Swap the shallot
