Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing as they set with gentle heat, giving it body and richness.
- Butter
- Adds richness and a smooth, creamy mouthfeel to the dressing.
- Cornstarch
- Thickens the liquid as it heats, helping the dressing set smoothly.
- Vinegar
- Provides the sharp acidity that defines the dressing's tang.
- Milk
- Forms the liquid base that the eggs and cornstarch thicken.
The step that matters
Simmer without boiling while stirring constantly. Egg proteins set gently at simmering temperature, but boiling can curdle the eggs and leave the dressing grainy. Constant stirring spreads heat evenly so the cornstarch and eggs thicken smoothly.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, butter, milk, pepper, egg, vinegar, cream):
- Capsicumfits better
- Potatofits about as well
- Mustardthe original
- Asparagusfits about as well
Fit is the average pairing score against sugar, butter, milk, pepper, egg, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
