Stop guessing. Start understanding.
Every year, home kitchens produce thousands of jars of passata, giardiniera, sott’olio and preserves — and most of the people making them have no reliable way to know whether what they made is safe.
This book fixes that. Written by Zero-F, a cook trained in professional food production, thermal sterilisation and HACCP compliance, it brings industrial-grade food safety science down to the home kitchen — without a laboratory, without jargon, and without fear.
This is not a cookbook.The recipes exist to teach principles. By the end, you will be able to evaluate any preservation recipe — from any book, blog, or grandmother — and know whether it is safe before you make it.
You will learn:
– The three numbers that decide every preserve: pH, water activity, and temperature
– Water bath and pressure canning, step by step, with full processing tables
– Lacto-fermentation, vinegar, kombucha and fermented pastes
– The real risks of preserving in oil — and how to make sott’olio safely
– Salt curing, drying, and building a complete seasonal Italian pantry
– Safety reference tables, a glossary, and a year-round production calendar
The same science that governs commercial production. The scale of your own kitchen. A jar opened in February that tastes exactly like the August it was made.
For home production. The professional companion volume, Anatomy of a Preserve, covers commercial and regulatory contexts.
