Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the bulk of the relish and, once cooked down, its thick body.
- Coarse sea salt
- Draws moisture out of the tomatoes, firming them and reducing the water that would dilute the relish.
- Onions
- Add savory depth and sweetness as they soften and cook down with the tomatoes.
- Vinegar
- Adds acidity that gives the relish its tang and helps preserve it.
- Mustard seed
- Contributes sharp, pungent flavor that mellows during long cooking.
The step that matters
Drain the tomatoes after salting. Salt pulls water out of the tomatoes. Draining removes that liquid so the relish can thicken during boiling instead of turning watery and diluted.
Swap the tomato
How well each one fits the dish's main ingredients (onion, pepper, allspice, mustard, vinegar):
