Why it works: Mustard and celery 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 ↓
Salad Dressing
Ingredients

Mix mustard and remaining sugar, then add flour.
Beat in the eggs and gradually add the boiling vinegar mixture.

Finish

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the dressing as they cook, giving it a rich, set body.
- Flour
- Stabilises the mixture and adds body so the dressing thickens without separating.
- Sugar
- Balances the sharp vinegar and mustard with sweetness.
- Vinegar
- Provides the sharp acidity that defines the dressing's tang.
- Cream
- Adds richness and a smooth, creamy mouthfeel.
- Butter
- Adds fat for richness and smooth texture.
The step that matters
Cook in a double boiler until thick. Eggs thicken as they heat but can curdle or scramble if overheated, so gentle indirect heat in a double boiler keeps the dressing smooth while it sets.
Swap the celery
How well each one fits the dish's main ingredients (vinegar, sugar, flour, butter, egg, mustard, pepper):
- Tarragonfits better
- Capersfits better
- Cinnamonfits better
- Celerythe original
Fit is the average pairing score against vinegar, sugar, flour, butter, egg, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes.
