Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Main vegetable that gives the relish its bulk and body once salted and drained.
- Onions
- Add sweetness and savory depth, softening as they cook in the vinegar.
- Vinegar
- Provides the acidity that preserves the relish and gives it its sharp flavor.
- Mustard seed
- Adds sharp, pungent heat that defines the relish's flavor.
The step that matters
Drain and press the salted tomatoes dry. Salt draws water out of the tomatoes, and any moisture left behind dilutes the vinegar and weakens both flavor and keeping quality.
Swap the tomato
How well each one fits the dish's main ingredients (onion, mustard, pepper, ginger, clove, vinegar):
- Horseradishfits better
- Shallotfits better
- Broccolifits better
- Tomatothe original
Fit is the average pairing score against onion, mustard, pepper, ginger, clove, vinegar. Candidates are from the same food group and used in at least 100 recipes.
