Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the relish and soften into a tender, chunky texture when cooked.
- Silver-skin onions
- Add savory flavor and body, and release moisture that salting draws out.
- Vinegar
- Provides acidity that gives the relish its sharp, tangy character and helps preserve it.
- Brown sugar
- Balances the acidity with sweetness and adds depth of flavor.
- White mustard seed
- Contributes sharp, pungent flavor that mellows during cooking.
The step that matters
Pressing the salted mixture dry. Salt draws water out of the vegetables. Pressing removes that liquid so the relish cooks thick rather than watery, and the vinegar and sugar are not diluted.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, onion, cabbage, celery, vinegar, sugar, mustard):
- Horseradishfits better
- Broccolifits better
- Lettucefits better
- Tomatothe original
Fit is the average pairing score against pepper, onion, cabbage, celery, vinegar, sugar, mustard. Candidates are from the same food group and used in at least 100 recipes.
