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 during cooking, giving it a custard-like body.
- Butter
- Adds richness and a smooth, silky mouthfeel to the dressing.
- Cornstarch
- Thickens the dressing by swelling in heat and binding the liquid.
- Vinegar
- Provides the sharp acidity that balances the sugar and richness.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
The step that matters
Cooking the thickened dressing. Egg yolks can curdle if the mixture gets too hot or cooks too fast. Cooking gently while stirring keeps the custard smooth, and cornstarch helps stabilise it as it thickens.
Swap the celery
The recipe marks celery as optional. How well each one fits the dish's main ingredients (sugar, mustard, white pepper, butter, cream, vinegar, egg):
- Tarragonfits better
- Nutmegfits better
- Capersfits better
- Celerythe original
Fit is the average pairing score against sugar, mustard, white pepper, butter, cream, vinegar, egg. Candidates are from the same food group and used in at least 100 recipes.
