Pressure Canning

Essential for low-acid foods, pressure canning allows you to preserve vegetables, meats, and complete meals.

Safety Warning

Pressure canning requires precise procedures. Botulism can be fatal. Always follow tested recipes from reliable sources like the USDA Complete Guide to Home Canning.

Foods Requiring Pressure Canning

Vegetables: Green beans, corn, carrots, peas, potatoes
Meats: Chicken, beef, pork, fish
Soups and stews: Complete meals in jars
Beans and legumes: Dried beans, split peas
Low-acid combinations: Vegetable soups, meat sauces

Pressure Canner Types

Weighted gauge: Simple, reliable, less precise
Dial gauge: More precise, requires annual testing
Size considerations: 16-quart minimum, larger for efficiency

Pressure Canning Steps

Prepare canner: Check seals, test gauge annually
Add water: 2-3 inches in bottom of canner
Prepare food: Raw pack or hot pack methods
Fill jars: Follow headspace requirements precisely
Load canner: Don't overcrowd, ensure steam circulation
Vent steam: 10 minutes before adding weight
Process: Maintain pressure for full time required
Cool naturally: Don't force cooling, wait for pressure to drop
Remove jars: Let cool completely before testing seals

Dehydrating and Drying

One of humanity's oldest preservation methods, dehydrating concentrates flavors and nutrients while removing water that spoilage organisms need.

"And there was a famine in the land: and Abram went down into Egypt to sojourn there; for the famine was grievous in the land." - Genesis 12:10

Throughout Scripture, we see the importance of storing food for lean times. Dehydrating allows long-term storage without modern refrigeration.

Dehydrating Methods

Sun Drying

Free and traditional method
Best for high-sugar fruits and herbs
Requires 3+ days of hot, dry weather
Cover with cheesecloth to prevent insects
Bring inside at night to avoid moisture

Air Drying (Herbs)

Perfect for medicinal and culinary herbs
Bundle stems and hang in dry, well-ventilated area
Avoid direct sunlight for best color retention
Takes 1-4 weeks depending on humidity

Electric Dehydrators

Consistent temperature and airflow
Weather independent
Excalibur and NESCO are popular brands
Round units cheaper, square units more efficient

Oven Drying

Use lowest temperature (140-170°F)
Prop door open slightly for air circulation
Monitor closely to prevent over-drying
Good for small batches and testing

Best Foods for Dehydrating

Fruits: Apples, pears, grapes, berries, stone fruits
Vegetables: Tomatoes, peppers, onions, mushrooms
Herbs: Basil, oregano, thyme, rosemary
Meats: Jerky from lean cuts (beef, venison, turkey)
Leather: Fruit leather from purees

Dehydrating Tips

Uniform slicing: Even thickness ensures even drying
Pretreatment: Blanching or lemon juice prevents browning
Temperature control: Too high destroys nutrients and flavor
Storage: Airtight containers, vacuum sealing best
Testing doneness: Should be leathery, not brittle or moist

Fermentation

Ancient fermentation creates probiotics, preserves food, and develops complex flavors. These living foods support gut health and immune function.

Types of Fermentation

Lacto-Fermentation (Vegetables)

Salt brine method: Vegetables submerged in salt water
Dry salt method: Salt draws moisture from vegetables
Anaerobic environment: Keeps food below brine level
Time: 3 days to several months

Alcoholic Fermentation

Mead: Fermented honey water
Wine: Fermented fruit juices
Cider: Fermented apple juice
Kombucha: Fermented sweet tea

Dairy Fermentation

Yogurt: Cultured milk with beneficial bacteria
Kefir: Fermented milk drink
Cheese: Complex fermentation and aging process
Buttermilk: Cultured dairy product

Biblical Principles of Food Storage

"Go to the ant, thou sluggard; consider her ways, and be wise: Which having no guide, overseer, or ruler, Provideth her meat in the summer, and gathereth her food in the harvest." - Proverbs 6:6-8

Wisdom from Scripture

Joseph's seven years: Store abundance for lean times
Ant's example: Work diligently while opportunity exists
Stewardship: Don't waste what YHWH provides
Provision: Trust, but also prepare
Sharing: Preserved food helps neighbors in need

The Security of Self-Reliance

"She is like the merchants' ships; she bringeth her food from afar. She riseth also while it is yet night, and giveth meat to her household, and a portion to her maidens." - Proverbs 31:14-15

The virtuous woman of Proverbs 31 understood food security. In our modern context, mastering preservation techniques is both practical wisdom and spiritual obedience - providing for your household while reducing dependence on fragile supply chains controlled by corrupt systems.
