Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a smooth, creamy mouthfeel to the dressing.
- Cornstarch
- Thickens the liquid as it heats, giving the dressing body in place of eggs.
- Cream or milk
- Supplies liquid and creaminess, softening the sharpness of the vinegar.
- Vinegar
- Provides acidity that gives the dressing its tangy flavor.
- Sugar
- Balances the acidity of the vinegar with a touch of sweetness.
- Prepared mustard
- Adds sharp, aromatic flavor and helps the dressing taste savory.
The step that matters
Thicken with cornstarch. Cornstarch thickens only when heated and must be fully cooked to lose its raw starchy taste and reach full thickness. Adding it in the wrong amount or stopping too early can leave the dressing thin or floury, so add it gradually and cook until the consistency is reached.
Swap the mustard
How well each one fits the dish's main ingredients (butter, sugar, pepper, cream, vinegar):
- Capsicumfits about as well
- Mustardthe original
- Potatofits about as well
- Onionfits less well
Fit is the average pairing score against butter, sugar, pepper, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
