Our Methodology: Data Sources & Content Philosophy
At SafeCanner.io, transparency and safety are our highest priorities. We want you to understand exactly how our content is created so you can use our tools and guides with confidence. Our methodology is built on two pillars:
1. Our Data: The Unalterable Numbers
All quantitative data points on this website are sourced directly from official, scientifically-tested guidelines. This includes:
- Processing times
- Required pressures (PSI)
- Jar headspace measurements
- Acidulation quantities (e.g., amount of lemon juice)
Our primary source is the National Center for Home Food Preservation (NCHFP), which publishes the United States Department of Agriculture's (USDA) Complete Guide to Home Canning. We treat this data as scientific fact. It is non-negotiable.
2. Our Guides: The Explanatory Words
While the data provides the "what," our articles aim to explain the "how" and "why" in the clearest way possible. Our step-by-step guides, explanations, and FAQ sections are our original works.
Our writing process involves:
- Starting with the official guidelines to establish the core safety-critical steps.
- Consulting best practices from respected authorities in the home preservation community (such as Ball Canning, Serious Eats, etc.) to learn how to best explain these steps in a practical, easy-to-follow manner.
- Synthesizing this information into a new, comprehensive guide written in our own words, designed to support, not replace, a complete, tested recipe.
We believe this combination of official data and clear, helpful explanation provides the most responsible and valuable resource for the modern home canner.
