Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Emulsify the oil and vinegar to form a thick, smooth sauce.
Olive oil
Provides fat that gives the sauce its rich body and mouthfeel.
Mustard
Helps hold the oil and vinegar together as an emulsion and adds sharpness.
Tarragon vinegar
Adds acidity and a sharp, herbal aroma to balance the rich oil.

The step that matters

Adding the oil and vinegar. Oil must be added slowly while stirring, alternating with vinegar, so the yolks can emulsify it. Adding too much at once can break the sauce into a greasy, separated mixture.

Fit is the average pairing score against egg, mustard, olive, tarragon, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
