How to use a canning book safely
- Check the publication date and compare older instructions with current authoritative guidance.
- Use recipes that specify jar size, preparation, processing method, time, pressure when applicable, and altitude adjustments.
- Do not improvise ingredient proportions in recipes where acidity or heat penetration controls safety.
Additional manufacturer title
A published recipe is not automatically a laboratory-tested recipe. When a book conflicts with current USDA, NCHFP, extension, or equipment-manufacturer safety guidance, follow the current authoritative source.
