The Canning Primer

Getting Started

Start right here, with no experience assumed. Home canning is simply sealing food in jars so it stays good on the shelf for months: as a processed jar cools, the lid is pulled down into a vacuum seal that keeps spoilage out. The big decision for any food is acidity, because it sets the method. High-acid foods like jams, fruit, and pickles are safe to process in a boiling water bath, while low-acid foods like plain vegetables and meats need a pressure canner to reach a safe temperature. The one rule that never changes is to follow a current, tested recipe for the exact times. These guides walk you through that foundation gently, so the whole craft feels approachable rather than intimidating.
