Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Provide the main acidic, aromatic body of the pickle and its sharp flavour.
- Coarse sea salt
- Draws moisture out of the lemons and helps preserve the mixture.
- Horseradish
- Adds pungent heat and sharpness that mellows during the long rest.
- Vinegar
- Provides acidity that preserves the pickle and carries the flavours of the spices.
- Mustard flour
- Adds a sharp, pungent bite and helps thicken the mixture.
The step that matters
Bring the mixture to a boil for 20 minutes. Boiling with vinegar and salt helps kill microorganisms and extracts spice flavour, while overheating can dull the sharp lemon and mustard notes.
