Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the dressing as it cooks and gives it a rich, creamy body.
- Vinegar
- Adds acidity that gives the dressing its tangy flavor.
- Milk
- Adds moisture and creaminess, softening the sharpness of the vinegar.
- Brown sugar
- Adds sweetness that balances the acidity of the vinegar.
- Butter
- Adds fat that gives the dressing a smoother, richer mouthfeel.
The step that matters
Cook over low heat while stirring constantly. Egg proteins set and thicken gently at moderate heat. High heat or stopping to stir can scramble the egg, leaving lumps and a grainy texture instead of a smooth, thick dressing.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, pepper, butter, vinegar, milk):
- Capsicumfits better
- Potatofits about as well
- Mustardthe original
- Asparagusfits about as well
Fit is the average pairing score against egg, sugar, pepper, butter, vinegar, milk. Candidates are from the same food group and used in at least 100 recipes.
