Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites fold in air for a lighter, frothier texture in the finished dressing.
- Flour
- Starch thickens the liquid as it boils, giving the dressing body.
- Vinegar
- Provides the acidity that gives the dressing its tangy flavor.
- Butter
- Adds fat for richness and a smoother mouthfeel.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
The step that matters
Boil all together, stirring constantly until thickened. Flour starch thickens only when heated with liquid, and constant stirring prevents lumps and scorching on the bottom of the pan. Stopping too early leaves the dressing thin.
Swap the celery
How well each one fits the dish's main ingredients (vinegar, milk, sugar, butter, mustard, pepper, flour):
- Cinnamonfits better
- Tarragonfits better
- Capersfits better
- Celerythe original
Fit is the average pairing score against vinegar, milk, sugar, butter, mustard, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
