What each ingredient does
- Tomatoes
- Provide the main body, flavour and acidity of the preserved product.
- Salt
- Seasons the tomatoes and adds flavour to the preserved product.
- Sugar
- Balances the acidity of the tomatoes and rounds out their flavour.
The step that matters
Processing time and pressure for the jar size. Tomatoes are borderline acidic, so they need enough heat for long enough to destroy harmful microorganisms. Pint and quart jars need different times, and too short a process can leave the contents unsafe to store at room temperature.
