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
- Potatoes
- Form the bulk of the salad and absorb the dressing's flavour.
- Salad oil
- Carries fat-soluble flavours and gives the dressing a smooth, rich mouthfeel.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil and sugar.
- Prepared mustard
- Emulsifies the oil and vinegar so the dressing holds together rather than separating.
The step that matters
Gradually whip in the vinegar. Adding vinegar slowly, a teaspoon at a time, lets the oil and mustard emulsify into a stable dressing. Pouring it in all at once can cause the mixture to separate and become thin and greasy.
Swap the potato
How well each one fits the dish's main ingredients (sugar, mustard, pepper, celery, vinegar):
- Horseradishfits better
- Capsicumfits better
- Lettucefits better
- Potatothe original
Fit is the average pairing score against sugar, mustard, pepper, celery, vinegar. Candidates are from the same food group and used in at least 100 recipes.
