Why it works: Mustard and horseradish match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,832 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the bulk of the sauce and provide its main body and moisture.
- Vinegar
- Adds acidity that gives the sauce its tang and helps preserve it.
- Brown sugar
- Adds sweetness that balances the acidity and spice.
- Horseradish
- Contributes a sharp, pungent bite to the sauce.
- Onion
- Adds savory depth and body as it softens during cooking.
- Red peppers
- Add sweetness, colour and a mild heat to the sauce.
The step that matters
Simmer until well combined and heated through. Simmering long enough lets the raw vegetables soften and the spices and acid blend into one sauce. Stopping early can leave it harsh and uneven, while the sauce thickens as moisture evaporates.
