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 ↓
Celery Mayonnaise
Ingredients
Directions
Make the dressing
Beat the egg yolks until very light.
Add the vinegar and water to the yolks.
Blend the mustard, flour, salt, and sugar, then add to the mixture.
Place the mixture in a rounded bottom enamel bowl and set it in boiling water.
While the water boils, whip the egg mixture with a wire egg beater until thick and smooth.
Remove from heat and add the butter or oil, then chill.
Finish
Once cold, mix in the chopped celery.
For a perfect finish, add a little additional whipped cream if desired.

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
- Egg yolks
- Thicken the dressing and emulsify it into a smooth, rich base.
- Vinegar
- Adds acidity that sharpens the flavor and balances the sweetness.
- Flour
- Stabilizes the cooked mixture so it thickens and holds together.
- Sugar
- Balances the acidity and adds sweetness.
- Butter or oil
- Adds fat that gives the dressing a smoother, richer texture.
- Celery
- Adds crisp texture and fresh, aromatic flavor to the dressing.
The step that matters
Thickening over boiling water. Egg yolks thicken gently as they heat, but if they get too hot they can scramble into lumps. Keep the bowl over steadily boiling water and whip constantly until the mixture is thick and smooth.
Swap the celery
How well each one fits the dish's main ingredients (egg, vinegar, mustard, flour, sugar, butter, cream):
- Capersfits better
- Tarragonfits better
- Nutmegfits better
- Celerythe original
Fit is the average pairing score against egg, vinegar, mustard, flour, sugar, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
