Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken as they cook gently, giving the dressing a creamy body.
- Chicken fat or batter
- Adds richness and body, helping the dressing feel smooth and full.
- Vinegar
- Provides acidity that gives the dressing its sharp, tangy flavor.
- Sugar
- Balances the sharpness of the vinegar with gentle sweetness.
- Mustard
- Adds sharp flavor and helps emulsify the dressing.
The step that matters
Stir continuously over boiling water. Egg proteins set when heated, so constant stirring over gentle heat keeps the mixture smooth and creamy. If left still, the eggs can scramble and turn lumpy.
Swap the mustard
How well each one fits the dish's main ingredients (egg, chicken, vinegar, sugar, pepper):
- Capsicumfits better
- Mustardthe original
- Asparagusfits less well
- Cucumberfits less well
Fit is the average pairing score against egg, chicken, vinegar, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
