Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the pickle and absorb the vinegar flavour as they sit.
- Peppers
- Add sharpness and aroma that complement the tomatoes in the brine.
- Sharp vinegar
- Acidity that preserves the pickle and gives it its tangy character.
- Cloves
- Add warm, aromatic spice that flavours the vinegar.
The step that matters
Soaking the tomatoes and peppers. Soaking in cold water for a full day draws out moisture and some of the sharp bitterness before the vinegar is added. Skipping or shortening it leaves the pickle wetter and harsher, and the vinegar cannot be fully absorbed evenly.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, vinegar, clove):
- Capsicumfits better
- Mustardfits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against pepper, vinegar, clove. Candidates are from the same food group and used in at least 100 recipes.
