How to Preserve Food Without Electricity
Compare shelf-stable purchasing, drying, canning, fermenting, root-cellar concepts, and other non-electric approaches.
Preparing for power loss does not require mastering every traditional preservation technique. The simplest first step is increasing foods that are already shelf stable, then learning one tested preservation method at a time.
First reduce refrigeration dependence

Drying
Drying is best approached as part of a system rather than as an isolated trick. Match the food, packaging, preparation needs and storage conditions to the emergency you are planning for. When a method controls pathogens, acidity, moisture or processing temperature, use a current tested recipe or official procedure rather than adjusting times, ratios or temperatures by intuition.
Canning
Canning is best approached as part of a system rather than as an isolated trick. Match the food, packaging, preparation needs and storage conditions to the emergency you are planning for. When a method controls pathogens, acidity, moisture or processing temperature, use a current tested recipe or official procedure rather than adjusting times, ratios or temperatures by intuition.
Fermentation and pickling
Fermentation and pickling is best approached as part of a system rather than as an isolated trick. Match the food, packaging, preparation needs and storage conditions to the emergency you are planning for. When a method controls pathogens, acidity, moisture or processing temperature, use a current tested recipe or official procedure rather than adjusting times, ratios or temperatures by intuition.
Cool storage and cellaring
Cool storage and cellaring is best approached as part of a system rather than as an isolated trick. Match the food, packaging, preparation needs and storage conditions to the emergency you are planning for. When a method controls pathogens, acidity, moisture or processing temperature, use a current tested recipe or official procedure rather than adjusting times, ratios or temperatures by intuition.
Safety sources to keep handy
For preservation methods where process details affect safety, use current research-tested guidance rather than improvising.
