The Canning Primer

Water-Bath Canning

This is the method for high-acid foods, the friendliest place for a beginner to start. It covers jams and jellies, most fruit, pickles, and tomatoes or salsa made from a tested recipe with the acid it specifies. The steps are simple to follow: prepare and warm your jars, fill them to the headspace the recipe gives, release air bubbles and wipe the rims, apply lids and bands, then process in a full, rolling boil for the listed time. Afterward you lift the jars out, let them cool undisturbed, and confirm the seals the next day. One detail beginners often miss is altitude: higher elevations need added processing time, so always check the adjustment in your recipe.
