Food preservation
Keep good food good — safely.
Choose a preservation method that fits the food, your equipment and how you plan to store it. Always follow a current, tested recipe for home canning.
Important safety rule: low-acid foods such as plain vegetables, beans and meat need a tested pressure-canning process for shelf-stable storage. A boiling-water canner is not a safe substitute. A pressure cooker is not automatically a pressure canner.
♨️
Water-bath canning
For tested high-acid recipes such as many fruit preserves, pickles and properly acidified foods. Use the exact recipe and processing time.
Read NCHFP guidance ↗🫙
Pressure canning
Required for low-acid foods intended for pantry storage. Jar size, pressure, time and altitude matter; do not improvise.
Read tested guidance ↗❄️
Freezing and chilling
Use freezer-safe packaging, label dates and keep refrigerated foods cold. Cool leftovers promptly in shallow containers.
Cold storage charts ↗🌬️
Drying and dehydrating
Learn safe preparation, drying and storage practices. Drying changes texture and shelf life; it does not make every food shelf-stable automatically.
NCHFP drying resources ↗🥒
Pickling and fermentation
Use tested acid ratios for vinegar pickles. For fermentation, follow reliable salt, temperature and time guidance.

Storage and labeling
Label contents and dates, rotate supplies and discard suspicious jars safely. Never taste food to check whether it is safe.
FoodSafety.gov ↗Before you can anything
- Start with a current, tested recipe from a trusted extension or food-safety source.
- Follow the specified jar size, headspace, pressure, processing time and altitude adjustment.
- Do not alter acidity, thickeners, ingredients or jar sizes unless the tested source permits it.
- A sealed lid does not prove safety. If you suspect spoilage, do not taste it.
Everyday appliances
Use the tools you already have.
You do not need a kitchen full of specialty gadgets. Start with the appliance you own and a clear, safe method.
🍲
Pressure cooker
Great for beans, soups, grains and tenderizing tougher cuts. Use the manual's fill limits and release instructions.
Not for canning⏲️
Slow cooker
Plan safe thawing, cooking and holding. Do not put frozen meat straight into a slow cooker; follow trusted time and temperature guidance.
🌪️
Air fryer
Small-batch roasting can crisp vegetables and reheat food. Avoid overcrowding and check doneness with a food thermometer when needed.
🔥
Oven and stovetop
Flexible basics for roasting, baking, simmering and one-pan meals. A thermometer is a useful low-cost safety tool.
🧊
Refrigerator and freezer
Keep the refrigerator at 40°F / 4°C or below and freezer at 0°F / −18°C. Organize food so older items are used first.
Storage chart ↗🍚
Rice and leftovers
Spread cooked rice in shallow containers, chill promptly and refrigerate. Do not leave cooked rice sitting at room temperature for hours.
Food safety basics ↗Food science made useful
Understand what is happening in the pot.
Simple science can help you cook better, reduce waste and make safer choices.
🌾 Starch, cooling and reheating
When cooked rice, potatoes and some other starchy foods cool, part of the starch can reorganize into a form called resistant starch. The amount varies by food and method. This does not make cooked food safe to leave unrefrigerated.
Practical rule: cool leftovers quickly in shallow containers, refrigerate promptly and reheat thoroughly.
🧪 Acidity and canning
Acidity is a key safety barrier in water-bath canning. Vinegar strength, ingredient proportions and tested processing times are not interchangeable guesses.
Practical rule: use tested recipes; do not reduce vinegar or change proportions unless the source specifically says it is safe.
🧊 Freezing and texture
Water expands as it freezes and can damage cell structure, making some foods softer after thawing. Packaging tightly helps protect quality.
🌡️ Temperature and microbes
Time and temperature affect microbial growth. Smell and appearance cannot reliably reveal every food-safety hazard.
Safe internal temperatures ↗Indoor and outdoor growing
Grow what fits your space.
A few pots of herbs or peppers can be a useful start. Match the plant to your light, climate, container and time.
🌶️
Peppers
Give peppers warmth, bright sun, drainage and steady moisture. Use a container with drainage holes and a pot large enough for the variety.
🌿
Kitchen herbs
Basil, parsley, chives and mint can be grown in containers. Mint spreads aggressively, so keep it in its own pot.
🥬
Greens and quick crops
Lettuce and some leafy greens can work in shallow containers and partial sun, especially in cooler weather.
🪴
Containers on a budget
Reuse sturdy food-safe containers only when they can drain freely and have not held chemicals. Never use containers that may leach harmful substances.
☀️
Light and watering
Watch the plant rather than the calendar. Check soil moisture, provide appropriate light and avoid leaving roots waterlogged.
🌱
Start small
Try one or two plants first. Track planting dates, sun exposure and harvests in the notepad to learn what works where you live.
