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 supply its main body and flavor.
- Onions
- Add savory bulk and sweetness that mellows as the sauce cooks.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
- Strong vinegar
- Provides acidity that preserves the sauce and sharpens its flavor.
The step that matters
Cook until tender. Cooking long enough softens the tomatoes and onions and lets the vinegar and spices blend. Stopping early leaves a raw, sharp taste and a chunky texture.
Flavor stand-ins for the mace
How well each one fits the dish's main ingredients (tomato, onion, sugar, mustard, clove, pepper, celery):
- Thymebetter flavor fit
- Allspicebetter flavor fit
- Tarragonbetter flavor fit
- Macethe original
Fit is the average pairing score against tomato, onion, sugar, mustard, clove, pepper, celery. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
