Step-by-Step Instructions
-
01
Salt curing: Meat and fish
Cover meat or fish completely in salt (about 1 pound salt per 5 pounds of meat). Pack tightly in a container. Refrigerate or keep below 40°F for 7-14 days. Rinse excess salt before eating. Properly salt-cured meat lasts months without refrigeration.
-
02
Solar dehydration: Fruits and vegetables
Slice food thin (1/4 inch or less). Arrange on a drying rack with airflow on all sides. Place in direct sun with good air circulation. Cover with cheesecloth to keep insects off. Most foods dry in 2-4 days of sun. The food is done when it's leathery with no moisture when squeezed.
-
03
Smoking: The dual-purpose method
Cold smoking (below 90°F) preserves without cooking. Hot smoking (above 165°F) cooks and preserves simultaneously. Build a small smoke chamber and maintain low, smoldering hardwood smoke for 6-24 hours depending on the food thickness.

04
Fermentation: Nature's preservative
Shred cabbage, add 2% salt by weight, pack into a jar, and press until liquid covers the cabbage. Cover loosely (gas must escape). Wait 1-4 weeks at room temp. The lactic acid bacteria preserve the food and add beneficial probiotics. This is how sauerkraut is made.

05
Root cellaring: Temperature storage
Root vegetables (potatoes, carrots, beets, turnips) store for months in a cool (32-40°F), humid (85-95%), dark space. A buried trash can, basement corner, or actual root cellar works. Layer vegetables in damp sand to maintain humidity.
Pro Tips
- Botulism thrives in low-oxygen, low-acid environments. Never can low-acid foods (meat, vegetables) without a pressure canner.
- Store dehydrated foods in airtight containers with oxygen absorbers. They'll last 1-2 years.
- Fermented foods get more nutritious over time. Vitamins C and B increase during fermentation.
- Combining methods (salt + smoke, dehydrate + vacuum seal) dramatically extends shelf life.
