Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled egg yolks
- Emulsify with the cream or oil, giving the dressing a thick, smooth body.
- Mustard
- Helps stabilise the emulsion and adds a sharp, pungent bite.
- Cream or pure oil
- Supplies the fat that gives the dressing its richness and body.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness of the fat.
The step that matters
Gradually add the cream or oil and vinegar. Adding the liquid slowly while mixing lets the yolk coat fat droplets finely, forming a stable emulsion. Adding it all at once can cause the dressing to separate and turn thin and greasy.
Swap the shallot
The recipe marks shallot as optional. How well each one fits the dish's main ingredients (egg, mustard, sugar, cream, vinegar, sauce, clove):
- Horseradishfits better
- Shallotthe original
- Capsicumfits less well
- Lettucefits less well
Fit is the average pairing score against egg, mustard, sugar, cream, vinegar, sauce, clove. Candidates are from the same food group and used in at least 100 recipes.
