⚠️ Important Safety Warning (VERY IMPORTANT)

🚫 Do NOT store fresh tomatoes in oil at room temperature
🚫 Do NOT can tomatoes without vinegar or lemon juice

These methods risk botulism, a dangerous foodborne illness.

❗ Acid is REQUIRED for shelf-stable canning.
❗ Oil + no acid + room temperature = unsafe.

Freezing avoids this risk entirely.
