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

What each ingredient does

Oil
Forms the body of the dressing, giving it richness and a smooth mouthfeel.
Egg yolks
Emulsifiers that bind the oil and vinegar so the dressing stays smooth and creamy.
Tarragon vinegar
Provides the acidity and the main tarragon flavour of the dressing.

The step that matters

Incorporating the egg yolks. Egg yolks help emulsify oil and acid into a stable, smooth dressing. Adding them too quickly or not stirring thoroughly can leave the oil separated and the texture greasy.

Swap the capers

How well each one fits the dish's main ingredients (tarragon, vinegar, egg, olive):

  1. Capersthe original
