Prepare
Finely chop the cabbage, onions, and cucumbers.
Pack the chopped vegetables in salt and let them sit overnight.
Soak and spice
In the morning, drain the mixture and soak it in vinegar and water for 1-2 days.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Forms the bulk of the pickle and keeps a firm, crisp texture.
- Cucumbers
- Adds crunch and fresh body to the pickle.
- Onions
- Adds savoury flavour and bulk to the mixture.
- Vinegar
- Provides the acidity that sharpens flavour and helps preserve the pickle.
- Sugar
- Adds sweetness that balances the sharp vinegar.
- Ground mustard
- Adds pungency and a sharp, warm aroma.
The step that matters
Draining after the salt and the soak. Salting draws water out of the vegetables, and draining well before adding the vinegar mixture stops the pickle from becoming watery. Thorough draining keeps the vegetables crisp and the vinegar flavour concentrated.
Swap the onion
