Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Provide the main structure and thickening as they set when gently heated.
- Butter
- Adds fat for richness and a smoother, rounder mouthfeel.
- Vinegar
- Supplies acidity that gives the dressing its sharp, tangy flavour.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Mustard
- Adds sharp flavour and helps keep the emulsion stable.
The step that matters
Cook the mixture in a double boiler until it thickens. Egg yolks thicken through gentle heat as their proteins set. Too much heat can scramble them into lumps, so keep the heat moderate and stir constantly.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, butter, vinegar, pepper):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Shallotfits less well
Fit is the average pairing score against egg, sugar, butter, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
