Why it works: Capsicum and vinegar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 10,160 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Pickled Red or Green Capsicums
Ingredients
Directions
Prepare
Wash the capsicums and remove the stems.
Pack them tightly in a clean jar.
Pickle and store
In a saucepan, combine vinegar, salt, sugar, and spices; bring to a boil.
Pour the hot mixture over the capsicums in the jar, ensuring they are fully submerged.
Seal the jar and let it cool before storing in a cool, dark place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Capsicums
- Provide the main vegetable body and crisp-tender texture of the pickle.
- Vinegar
- Supplies the acidity that preserves the peppers and gives the pickle its tang.
- Sugar
- Balances the sharpness of the vinegar and rounds out the flavour.
- Spices
- Add aroma and flavour to the pickling liquid.
The step that matters
Fully submerging the capsicums. Peppers poking above the pickling liquid can spoil, since air exposure allows mould and bacteria to grow. Keeping every piece under the brine, which is acidic, protects the pickle during storage.
Swap the capsicum
How well each one fits the dish's main ingredients (vinegar, sugar):
- Mustardfits better
- Capsicumthe original
- Cucumberfits about as well
- Beetrootfits less well
Fit is the average pairing score against vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
