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, giving the dressing a thick, creamy body.
- Olive oil
- Adds richness and fat, forming the body of the emulsified dressing.
- Mustard
- Helps hold the oil and vinegar together and adds sharp flavor.
- Vinegar
- Adds acidity and sharpness, and thins the dressing to the desired consistency.
The step that matters
Pour in the olive oil gradually. Adding oil slowly while beating lets the yolk emulsifier break it into tiny droplets. Pouring too fast can cause the dressing to split and stay oily instead of thickening.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, olive, egg, vinegar, pepper):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Tomatofits less well
Fit is the average pairing score against sugar, olive, egg, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
