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 into the mixture, giving the dressing a thick, creamy body.
- Olive oil
- Provides fat that, added slowly, forms a smooth emulsion and rich mouthfeel.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil and yolks.
- Whipped cream
- Folded in at the end, it lightens the texture and adds softness and body.
- Mustard
- Its compounds help stabilise the emulsion and add sharp flavour.
The step that matters
Adding the olive oil gradually. Oil must be added slowly while stirring so it disperses into tiny droplets held by the egg yolk. Adding it too fast can break the emulsion, leaving the dressing oily and separated.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, pepper, egg, olive, vinegar, cream):
- Capsicumfits better
- Mustardthe original
- Spinachfits about as well
- Cucumberfits about as well
Fit is the average pairing score against sugar, pepper, egg, olive, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
