Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the dressing and add richness and body as it thickens.
- Sugar
- Adds sweetness to balance the vinegar's acidity.
- Vinegar
- Adds acidity that gives the dressing its tang.
- Milk (in the method)
- Thins the mixture to a pourable dressing.
The step that matters
Adding the vinegar while stirring. Vinegar added while stirring is meant to thicken the mixture gradually. Adding it too fast or without stirring can cause the mixture to split or stay thin.
Swap the mustard
How well each one fits the dish's main ingredients (pepper, sugar, egg, vinegar):
- Capsicumfits better
- Mustardthe original
- Cucumberfits less well
- Cabbagefits less well
Fit is the average pairing score against pepper, sugar, egg, vinegar. Candidates are from the same food group and used in at least 100 recipes.
