Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks mashed with vinegar and butter form a smooth, creamy dressing that binds the salad.
- Melted butter
- Adds fat and richness, helping the yolk mixture become smooth and silky.
- Vinegar
- Adds acidity that brightens the flavor and balances the richness of the yolks and butter.
- Mustard
- Adds sharp flavor and pungency that cuts through the richness of the dressing.
- Celery
- Adds crisp texture and fresh, mild flavor to the chicken mixture.
The step that matters
Mashing the yolks smooth with vinegar and butter. If the yolks are not mashed fine and the butter is not fully incorporated, the dressing stays grainy and uneven instead of creamy. Stirring until smooth lets the fat and yolk emulsify evenly before it is poured over the chicken.
Swap the celery
How well each one fits the dish's main ingredients (chicken, egg, mustard, pepper, vinegar, butter):
- Tarragonfits better
- Capersfits better
- Dillfits about as well
- Celerythe original
Fit is the average pairing score against chicken, egg, mustard, pepper, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
