What each ingredient does
- Green peppers
- Form the main body of the pickle and keep their crisp-tender texture when packed in vinegar.
- Red peppers
- Add colour and mild sweetness to the finished pickle.
- Yellow sweet peppers
- Add colour and mild sweetness to the finished pickle.
- Vinegar
- Provides the acidity that preserves and sharpens the peppers.
The step that matters
Dilute strong vinegar before covering the peppers. Very strong vinegar can overpower the peppers and make them harsh; diluting it with an equal amount of cold water balances the acidity so the peppers stay palatable.
