A pressure canner is the only safe way to preserve low acid food at home. Meat, poultry, fish, beans, corn and stock carry no acidity to hold botulism spores back, and a boiling water bath never gets hot enough to deal with them. A pressure canner holds food above boiling point, at around 116 degrees, which is the temperature that makes the difference.

What that buys is a pantry rather than a freezer. Meat bought cheap in bulk, a glut of beans, a weekend of stock or bolognese, all sitting on a shelf at room temperature for years, through a blackout and without running a chest freezer to hold them.

The Canner

We stock one canner, deliberately. The Presto 23 quart, roughly 21 litres, built to our specification with a stainless steel base that works on induction as well as gas and electric, a dial gauge, and a three piece weighted regulator included rather than sold separately. It is the size that handles a full batch of quart jars in one run, and it doubles as a large pressure cooker between seasons.

Parts and Spares

A canner is a lifetime tool if the wearing parts are available, so we carry them properly. Sealing gaskets, overpressure plugs, vent pipes, interlock assemblies, dial gauges and their compression washers, racks, and both body and cover handles, alongside parts for All American canners. A gasket that perishes mid harvest should cost you a few days, not the whole machine.

Gauges are worth a word. A dial gauge gives you a live reading and can be checked for accuracy over time, while a weighted regulator rocks at a set pressure and needs no calibration at all. Our canner ships with both, which means you can run whichever suits you and cross check one against the other. Altitude matters too: above 300 metres you increase pressure to compensate, and the instruction book sets out by how much.

If you are starting from nothing, the bundles pair the canner with jars and the tools you will reach for immediately, in Ball Mason, Weck or Le Parfait. Otherwise choose jars separately from pressure canner jars, which are the ones rated for this job, and note that waterbath jars are a different thing. Ball Mason covers most pantries, and lifters, funnels and bubble removers live in jar accessories.
