Cross-Regional — Preservation
Using unripe or poor-quality tomatoes (the preserved product can't be better than the raw ingredient). Insufficient water-bath processing (botulism risk—process for at least 30-40 minutes). Not sterilising bottles properly. Adding too much basil or other aromatics (they can ferment). Storing in direct light (degrades colour and flavour).
