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 of the sauce once chopped.
- Vinegar
- Adds acidity that gives the sauce its sharp flavor and helps preserve it.
- Ground mustard
- Adds pungent, sharp flavor that balances the sweetness and acidity.
- Sweet peppers
- Contribute bulk, mild sweetness, and fresh vegetable flavor.
- Celery
- Adds crisp texture and a fresh, savory vegetable note.
The step that matters
Let the chopped tomatoes drip for 30 minutes. Draining removes excess free liquid from the tomatoes. Without it, the sauce can be watery and dilute the vinegar and seasoning, weakening flavor and texture.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, celery, mustard, vinegar, sugar):
- Horseradishfits better
- Capsicumfits better
- Lettucefits better
