Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Make up the bulk of the relish, providing body and a tart, fresh vegetable base.
- Coarse sea salt
- Draws water out of the vegetables, firming them and concentrating flavour before pickling.
- White mustard seed
- Adds a sharp, pungent flavour and crunch to the pickled vegetables.
- Ground mustard
- Adds pungency and flavour that blends into the vinegar and vegetables.
- Vinegar
- Acidity preserves the vegetables and gives the relish its sharp, tangy character.
The step that matters
Squeezing out the brine. Salted vegetables release a lot of liquid. Removing it before repacking keeps the relish from becoming watery and lets the vinegar penetrate and preserve it properly.
