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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil into the mixture and set the sauce into a thick, smooth body.
- Salad oil or melted butter
- Supplies the fat that, dispersed in droplets, gives mayonnaise its rich texture.
- Mustard
- Helps hold the oil and water phases together, stabilizing the emulsion.
- Vinegar
- Adds acidity for sharp flavor and thins the sauce to a cream-like consistency.
The step that matters
Adding the oil gradually. Oil must be added slowly so it breaks into fine droplets that the egg yolk can emulsify. Added too fast, the emulsion breaks and the sauce separates into oily liquid.
Swap the celery
How well each one fits the dish's main ingredients (egg, mustard, sugar, butter, vinegar, pepper):
- Tarragonfits better
- Capersfits better
- Cinnamonfits better
- Celerythe original
Fit is the average pairing score against egg, mustard, sugar, butter, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
