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 and tart flavour that forms the relish base.
- Cabbage
- Adds crunch and body that holds its texture through pickling.
- Vinegar
- Acidity that preserves the vegetables and gives the relish its sharp tang.
- Coarse sea salt
- Draws water out of the vegetables, softening them and concentrating flavour.
- Mustard seed
- Adds pungent, sharp aroma and a mild bite to the relish.
The step that matters
Salting overnight and checking the salt. Salt draws moisture out of the chopped vegetables, so they soften and stay crisp rather than watery. Too much salt leaves the relish harsh, which is why the record says to squeeze out excess when it tastes too salty.
