Frequently asked questions
Can I change the ingredients or process?
Only make changes expressly permitted by the authoritative source. Do not increase onions, peppers, mushrooms, oil, or other low-acid ingredients; do not water-bath can or thicken. Optional mushrooms may be omitted.
What if a jar does not seal?
Refrigerate promptly, or reprocess within 24 hours using a new lid and the complete tested process if the source and current food-safety guidance permit.
How this recipe compares
Unlike acidified plain tomatoes, this mixed-vegetable sauce requires pressure canning because of its tested low-acid ingredient load.
Troubleshooting
If pressure falls below the required level, return the canner to pressure and restart the complete processing time.
Discard any jar that is leaking, bulging, spurting, moldy, or otherwise shows signs of spoilage. Never taste food to determine safety.
