The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and vinegar barely smell alike, yet cooks put them together in 12,922 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the oil and vinegar, holding the dressing together and giving it body.
- Oil
- Provides fat that, dispersed into droplets, makes the dressing rich and thick.
- Tarragon vinegar
- Adds acidity and flavor, and thins the mixture to a creamy texture.
The step that matters
Gradually add the oil while stirring constantly. Oil must be added slowly so it breaks into fine droplets that the egg yolk can emulsify. Adding it too fast causes the mixture to separate and fail to thicken.
Swap the tarragon
How well each one fits the dish's main ingredients (egg, pepper, vinegar):
- Tarragonthe original
- Dillfits about as well
- Parsleyfits less well
- Allspicefits less well
Fit is the average pairing score against egg, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
