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 pickle and absorb the vinegar and spice flavours.
- Cucumbers
- Add crisp, watery texture that holds up to the vinegar brine.
- Onions
- Add savoury bulk and a sharp, aromatic note that mellows in the brine.
- Salt
- Draws water out of the chopped vegetables, helping them drain and firm up.
- Vinegar
- Acidifies the brine, preserving the vegetables and giving the pickle its sharpness.
- Brown sugar
- Balances the vinegar's sharpness with sweetness and a molasses depth.
- Mustard seed
- Adds pungent, slightly bitter heat that becomes milder as it steeps.
The step that matters
Salting and draining overnight. Salt draws out excess water from the chopped vegetables. Draining well before adding the hot brine keeps the pickle from being diluted and helps it stay firm rather than soft.
Swap the onion
