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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Provide the main body and liquid base of the sauce.
- White onions
- Add sharp, savoury bulk that mellows during the overnight rest.
- Brown sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Provides acidity that preserves the sauce and gives it its tang.
- White mustard seed
- Adds pungent heat and a bit of texture to the sauce.
The step that matters
Salt the mixture and drain overnight. Salt draws water out of chopped vegetables through osmosis. Draining afterward removes that liquid, so the sauce stays thick rather than watery once bottled raw.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, celery, mustard, sugar, vinegar):
- Capsicumfits better
- Lettucefits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, celery, mustard, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
