Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young onions
- Provide the main vegetable bulk and a sharp, savoury flavour once pickled.
- Sour apples
- Add natural tartness and a crisp texture to the pickling mixture.
- Fresh cucumbers
- Contribute crunch and moisture that the brine softens and flavours.
- Coarse sea salt
- Draws moisture out of the vegetables and seasons the pickles.
- Vinegar
- Provides acidity that preserves the vegetables and gives the pickles their tang.
