Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the olive oil and form the creamy body of the dressing.
- Olive oil
- Adds richness and smooth fat that gives the dressing its body.
- Vinegar
- Adds acidity and thins the mixture to a mayonnaise-like consistency.
The step that matters
Gradually stir in the olive oil until smooth. Adding the oil slowly lets the mashed yolk emulsify it, so the dressing stays smooth and thick instead of separating into greasy droplets.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, pepper, olive, vinegar):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Tomatofits less well
Fit is the average pairing score against egg, sugar, pepper, olive, vinegar. Candidates are from the same food group and used in at least 100 recipes.
