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 give it body and fresh tomato flavor.
- Onions
- Add savory depth and body as they soften during cooking.
- Vinegar
- Provides acidity that sharpens the flavor and helps keep the sauce stable.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Horseradish
- Contributes a sharp, pungent heat that gives the sauce its bite.
- Green peppers
- Add a fresh, slightly bitter vegetable flavor and extra body.
The step that matters
Boil for the full 30 minutes. Boiling the chopped vegetables with the vinegar and spices for the full time lets the vegetables soften and the spice flavors spread through the sauce. Stopping early can leave the sauce tasting raw and sharp.
