Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard
- Provides the main sharp, pungent flavor and body of the condiment.
- Brown sugar
- Adds sweetness that balances the sharpness of the mustard and vinegar.
- Hot vinegar
- Adds acidity that sharpens flavor and helps the mustard reach a pourable consistency.
The step that matters
Letting it sit for a day. Mustard's pungency is harsh when freshly mixed. Resting lets the flavors blend and mellow, so the result tastes more balanced than it does right after mixing.
Swap the mustard
How well each one fits the dish's main ingredients (pepper, sugar, vinegar):
- Capsicumfits better
- Mustardthe original
- Cabbagefits less well
- Cucumberfits less well
Fit is the average pairing score against pepper, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
