Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the bulk and body of the pickle once their excess juice is pressed out.
- Onions
- Add sharp, savoury flavour and aromatic depth as they soften in the vinegar mixture.
- Brown sugar
- Adds sweetness that balances the acidity of the vinegar and tomatoes.
- Vinegar
- Provides the acidity that gives the pickle its tang and helps keep it stable.
- Mustard seed
- Contributes a sharp, pungent bite that cuts through the sweetness.
- Ground cinnamon
- Adds warm aroma and a sweet spice note to the pickle.
The step that matters
Drain the chopped tomatoes. Pressing out the excess juice keeps the pickle thick rather than watery, and stops the liquid from diluting the vinegar and sugar balance.
