Canning, fermenting, drying, freezing, curing and cellaring - grounded in USDA, NCHFP and CDC science, not folklore.
What you'll learn
Decide for any food whether it belongs in the fridge, the freezer, the pantry, or the cellar - and when no safe pantry option exists at all
Recognize the four conditions Clostridium botulinum needs to make toxin, and remove at least one of them every time
Apply the pH 4.6 boundary to tell acid foods (water-bath safe) from low-acid foods (pressure-canning only)
Run a boiling-water canner correctly: headspace, bubble removal, fingertip-tight bands, full rolling boil before the timer starts
Operate a true pressure canner with confidence - venting pure steam 10 minutes, timing only at correct pressure, cooling naturally to zero
Adjust for altitude the right way for each canner type: add time for water-bath, add PSI for pressure
Freeze for quality using blanching, air removal, and thin flat packs, and know the real shelf windows
Dry fruit, vegetables, herbs, and jerky to correct moisture endpoints, condition them, and add the 160F kill step jerky requires
Ferment sauerkraut and pickles by weighed-salt ratio at the right temperature, and tell a healthy ferment from one you must discard
Make jam and jelly that sets - the fruit, pectin, acid and sugar quartet, the 220F gel point, and why cutting sugar wrecks both set and safety
Handle the high-risk methods honestly: curing with Prague Powder, hot-smoking to safe internal temps, root cellaring, and garlic-in-oil
Build a household system with labels, batch records, a monthly audit, failure diagnosis, and a safe disposal routine for any suspect jar
Requirements
A working kitchen and a willingness to follow tested processes exactly, without improvising the safety-critical steps
An appliance thermometer for your fridge and freezer, and an instant-read thermometer for jerky and smoking
For the canning sections: jars, two-piece lids, and a boiling-water or atmospheric steam canner for acid foods
For low-acid foods: a true pressure canner that holds quart jars upright - an Instant Pot or pressure cooker will not do
For curing and smoking: a kitchen scale and proper cure salts, bought before you attempt anything in that section
No math, chemistry, or food-science background needed - every figure is explained as it comes up
DescriptionThis course contains the use of artificial intelligence. The narration uses an AI text-to-speech voice, and the slides, animations, scripts, and written materials were produced with the help of AI tools. Every factual claim - dates, figures, and regulatory details - was checked against primary and authoritative sources and reviewed by a human for accuracy.
Most home preservation advice is a coin flip. Half of it comes from a tested USDA process; the other half comes from a relative's handwritten card, a blog with a pretty photo, or a video that skips the one step that keeps you out of the hospital. The trouble is that bad canning rarely announces itself. A jar of green beans sealed the wrong way looks identical to one sealed the right way, and botulinum toxin has no smell, no taste, and no color. So this course starts where the danger is real and works outward from there.
It is built around a single idea: the process is the safety control, not the seal or the smell or the look of the finished jar. Once you understand why pressure canning exists, why pH 4.6 is the line you never cross, and how water activity and temperature actually limit what can grow, the dozens of rules stop being arbitrary and start making sense. You learn the forgiving methods first - refrigeration, freezing, drying - then move into fermentation, the two kinds of canning, sweet preserves, and the higher-risk edges like curing, smoking, and storing garlic in oil. Every number traces back to USDA, NCHFP, CDC, and university extension sources, re-anchored to Fahrenheit and PSI the way the primary guidance publishes them.
By the end you won't be following recipes on faith. You will be able to look at any food coming out of your garden or off the shelf, name its hazard, pick the right method, run a tested process exactly, and store the result so it stays both safe and good. The course closes with worked decision examples and a graduated practice plan that ramps you from labeling and freezing up to pressure canning, so you build the skill at a pace that never gets ahead of what you actually know. All safety figures are current as of mid-2026.
Who this course is for
Home cooks who want to put up a harvest, a sale-priced bulk buy, or a weekend's batch cooking without guessing
Gardeners and allotment holders facing more zucchini, tomatoes, or beans than any household can eat fresh
Homesteaders building a full preservation skill set across freezing, drying, fermenting, canning, curing, and cellaring
Preppers who want shelf-stable food that's actually safe, stored and rotated on a system they can trust
Anyone handed a family canning recipe who has quietly wondered whether it's safe to follow
