Why it works: Celery and mustard are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Cold Slaw Dressing
Ingredients
Directions
Make the dressing base
In a tin cup, combine vinegar and celery seed, then place on the stove to boil.
In a separate bowl, mix the beaten eggs, butter, pepper, salt, and mustard.
Once the vinegar boils, pour it slowly into the egg mixture while stirring quickly.
Return the mixture to the heat for a few minutes, stirring to prevent curdling, then set aside to cool.
Finish
When completely cool, add olive oil or thick cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs thicken the dressing as they cook gently, giving it a creamy body.
- Vinegar
- Provides the sharp acidity that gives the dressing its tang.
- Butter
- Adds richness and a smooth mouthfeel to the dressing.
- Olive oil or thick cream
- Adds fat and body, softening the sharpness of the vinegar.
The step that matters
Returning the mixture to the heat. Eggs can curdle if overheated. Stirring constantly over gentle heat lets the egg proteins set smoothly, so the dressing stays creamy rather than grainy.
Swap the celery
How well each one fits the dish's main ingredients (vinegar, egg, butter, pepper, mustard, olive):
- Tarragonfits better
- Capersfits better
- Parsleyfits better
- Celerythe original
Fit is the average pairing score against vinegar, egg, butter, pepper, mustard, olive. Candidates are from the same food group and used in at least 100 recipes.
