Sovereignty Module: Preserve the Harvest
Complete Food Preservation: Every Method from Salt to Smoke to Fermentation
Preservation transforms seasonal abundance into year-round food security. This campaign covers every preservation method available without electricity.
Chapter 1: Preservation Methods Compared
| Method | Shelf Life | Equipment Needed | Energy Required | Best For |
|---|---|---|---|---|
| Drying/dehydration | 6-12 months | Racks, sun or fire | Low (sun) to moderate (fire) | Meat, fruit, herbs, vegetables |
| Smoking | 2-6 months (cold), 1-4 weeks (hot) | Smokehouse | Moderate (sustained fire) | Meat, fish |
| Salt curing | 6-12+ months | Salt, containers | None (after salting) | Meat, fish, vegetables |
| Fermentation (lacto) | 6-12+ months | Crocks, salt | None | Vegetables, dairy, beverages |
| Vinegar pickling | 1-2 years | Vinegar, containers | Low (making vinegar) | Vegetables, eggs, meat |
| Sugar preservation (jam) | 1-2 years | Sugar/honey, jars | Moderate (cooking) | Fruit |
| Fat/oil sealing (confit) | 3-6 months | Fat/oil, containers | Moderate (rendering) | Meat, vegetables |
| Root cellar storage | 3-8 months | Underground space | None | Root vegetables, apples, cabbage |
| Freeze (natural, winter) | Months (while frozen) | Cold climate | None | Meat, any food (seasonal) |
| Canning (water bath) | 1-5 years | Jars, lids, pot | Moderate (boiling) | Fruit, pickles, jams, tomatoes |
| Canning (pressure) | 1-5 years | Pressure canner, jars | Moderate | Meat, vegetables, soups |
Chapter 2: Salt Curing
| Method | Salt Ratio | Time | Product | Shelf Life |
|---|---|---|---|---|
| Dry cure (meat) | 3-5% of meat weight + time | 1-2 weeks per inch of thickness | Bacon, ham, jerky | 3-12 months |
| Brine cure (wet) | 10-15% salt solution | 1-4 weeks (depending on size) | Corned beef, salt pork, pickles | 6-12 months |
| Heavy salt pack | 25-33% salt by weight | 2-4 weeks | Salt fish, salt pork (long-term) | 1-2 years |
| Salt + smoke combination | 3-5% salt + cold smoke 1-4 weeks | 2-6 weeks total | Country ham, smoked salmon | 6-12 months |
| Salt + sugar cure | 2-3% salt + 1-2% sugar | 1-2 weeks | Bacon, gravlax | 2-4 weeks (refrigerated) |
Salt curing science: Salt draws moisture out of food (osmosis) and into the salt. Bacteria need moisture to grow. Below 25% moisture = most bacteria cannot survive. Salt also directly inhibits bacterial enzymes.
Chapter 3: Smoking
| Type | Temperature | Duration | Smoke Source | Result |
|---|---|---|---|---|
| Cold smoking | 60-90°F | 1-4 weeks | Smoldering hardwood sawdust | Preserved, raw texture (must be salt-cured first) |
| Warm smoking | 100-150°F | 4-24 hours | Low fire + chips | Partially cooked, shorter preservation |
| Hot smoking | 150-300°F | 2-8 hours | Active fire + chips | Fully cooked, eat immediately or short storage |
Best smoking woods: hickory (strong, classic), oak (medium, versatile), apple/cherry (mild, sweet), maple (mild, sweet), alder (light, fish). NEVER use: pine, spruce, cedar, or any resinous wood (toxic compounds, bitter taste).
Smokehouse construction: 1. Small enclosed structure (4×4×6 feet minimum). 2. Fire pit OUTSIDE or below (cold smoke) or inside at base (hot smoke). 3. Smoke pipe connecting fire to chamber (cold smoke). 4. Hanging racks/hooks inside. 5. Ventilation at top (adjustable). 6. Draft control at bottom.
Chapter 4: Lacto-Fermentation
| Food | Salt Ratio | Container | Time | Result |
|---|---|---|---|---|
| Sauerkraut | 2-3% of cabbage weight | Crock with weight | 2-6 weeks | Tangy preserved cabbage |
| Kimchi | 2-3% + spices | Jar or crock | 1-4 weeks | Spicy fermented vegetables |
| Pickles (cucumber) | 3-5% brine | Crock submerged in brine | 1-4 weeks | Sour pickles |
| Any vegetable | 2-3% salt by weight | Jar, submerged under brine | 1-6 weeks | Preserved, probiotic-rich |
| Yogurt/kefir | Culture + milk | Jar, warm (100-110°F) | 8-24 hours | Preserved dairy |
| Sourdough starter | Flour + water | Jar, room temperature | 5-7 days to establish | Leavening + preservation |
Key principle: Salt creates environment where ONLY beneficial Lactobacillus bacteria thrive. They produce lactic acid, which preserves food and prevents harmful bacteria. Submerge food under brine (no air contact) = anaerobic environment = safe fermentation.
Chapter 5: Drying and Dehydration
| Food | Method | Time | Done When | Storage |
|---|---|---|---|---|
| Meat (jerky) | Thin strips (1/4 inch), salt, dry in sun/smoke | 1-3 days | Bends without breaking, no moisture | Airtight container, cool/dark |
| Fruit (apple, berry) | Slice thin, dry in sun or over fire | 1-3 days | Leathery, no moisture when squeezed | Airtight container |
| Herbs | Hang in bundles, shade, good airflow | 1-2 weeks | Crumbles easily | Sealed jars, dark |
| Vegetables | Slice thin, blanch first (optional), dry | 1-3 days | Brittle, snaps | Airtight container |
| Fish | Split open, salt lightly, dry in sun/wind | 2-5 days | Hard, no flex | Cool, dry storage |
| Pemmican | Dried meat + rendered fat + dried berries | - | Shelf-stable mixture | Sealed containers (years) |
Pemmican: The ultimate survival food. 1. Dry meat completely (jerky). 2. Pound to powder. 3. Mix 1:1 with rendered fat (tallow). 4. Add dried berries (optional). 5. Press into cakes or store in containers. Shelf life: 1-5 years (some report decades). Complete nutrition: protein + fat + vitamins.
Chapter 6: Root Cellar Storage
| Produce | Temperature | Humidity | Shelf Life | Storage Method |
|---|---|---|---|---|
| Potatoes | 35-40°F | 90-95% | 4-6 months | Dark, in bins (no light = no greening) |
| Carrots | 32-35°F | 95-100% | 4-6 months | In damp sand or sawdust |
| Beets | 32-35°F | 95-100% | 3-5 months | In damp sand, trim tops |
| Onions | 32-40°F | 65-70% | 4-8 months | Dry, hanging in mesh bags |
| Garlic | 32-40°F | 60-70% | 6-8 months | Dry, braided or mesh bags |
| Apples | 32-35°F | 85-90% | 3-6 months | Wrapped individually, don't touch |
| Cabbage | 32-35°F | 90-95% | 3-4 months | Hang by root, or wrap in newspaper |
| Winter squash | 50-55°F | 50-70% | 3-6 months | Cure first (2 weeks at 80°F), then cool storage |
| Turnips/rutabaga | 32-35°F | 90-95% | 4-6 months | In damp sand |
Root cellar requirements: Underground (below frost line), ventilation (intake low, exhaust high), earth floor (maintains humidity), no light, separate from house (ethylene gas from fruit affects vegetables).
Reference Card
- Salt curing: 3-5% salt by weight for meat. Draws moisture out. Below 25% moisture = bacteria can't grow.
- Cold smoking: MUST salt-cure first. 60-90°F for 1-4 weeks. Hardwood only. Never resinous wood.
- Lacto-fermentation: 2-3% salt + submerge under brine (no air). Lactobacillus does the work. Safe, probiotic.
- Drying: thin slices, good airflow, low humidity. Done when no moisture remains. Store airtight, dark, cool.
- Pemmican: powdered jerky + rendered fat (1:1). Complete nutrition. Shelf life: years. Ultimate survival food.
- Root cellar: 32-40°F, high humidity (90%+), dark, ventilated, below frost line. Stores produce 3-8 months.
- Fermentation rule: if it smells bad (putrid, not sour), discard. Good fermentation smells sour/tangy, never rotten.
- Combination methods (salt + smoke + dry) give longest preservation. Country ham: salt + smoke = 1-2 years.
