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
- Tomatoes
- Provide the bulk and body of the sauce as they break down during cooking.
- Vinegar
- Adds acidity that gives the sauce its tang and helps preserve it.
- Brown sugar
- Adds sweetness that balances the acidity of the vinegar and tomatoes.
- Onions
- Add savory depth and aroma as they soften into the sauce.
- Green peppers
- Add fresh, slightly bitter vegetable flavor and some body to the sauce.
The step that matters
Cook until it thickens. Cooking drives off water and lets the chopped vegetables break down and reduce, so the sauce sets to the right consistency. Stopping too early leaves it thin, while overcooking can scorch the sugar on the bottom of the pot.
Swap the onion
