Preservation can extend the usefulness of a pantry, but technique matters. This is one area where historical anecdotes should never override modern safety guidance.

Use research-tested guidance

The National Center for Home Food Preservation describes itself as a source for current research-based recommendations covering canning, drying, fermenting, freezing and other preservation methods.

Drying

Drying removes moisture and can produce lightweight foods that do not require refrigeration. Packaging and storage remain important because dried foods can take moisture back up.

Canning

Use current tested recipes and the correct process for the food. Do not improvise canning times or treat an unverified historical method as equivalent to a tested modern process.
