DEHYDRATING

Dehydrating: Lightweight, Long-Lasting Storage

Why Dehydrating Food Still Works Today

Benefits of drying food: Drying is an old method that saves space and weight. It keeps most nutrients and can make flavors stronger.

Types of foods suitable for drying: Fruits, vegetables, herbs, and meats are great for drying. Popular dried foods include apples, tomatoes, herbs, and jerky.

3 Simple Drying Methods: Sun, Oven, or Dehydrator?

Sun drying: Good for hot, dry climates. Spread food on trays and cover with mesh to protect from bugs. Turn food regularly.

Oven drying: Use a low oven temperature (140°F) and place food on racks. Keep the oven door slightly open to let moisture escape.

Using a food dehydrator: A dehydrator gives consistent heat and airflow. Follow the manufacturer's instructions.

Storing & Rehydrating Dried Foods Made Simple

Proper storage methods for dried foods: Store dried foods in airtight containers in a cool, dark place. Use vacuum-sealer bags or Mason jars with oxygen absorbers and desiccant packets for longer storage.

How to rehydrate dried foods for use: Soak dried foods in water or broth until they return to their original texture. Use them in soups, stews, and other recipes.

FERMENTING

Fermenting: Boost Flavor & Gut Health

What Is Fermentation and Why Is It Healthy?

What is fermentation? Fermentation is when good bacteria turn sugars into acids, gases, or alcohol. This preserves food and adds nutrients and flavor.

Health benefits of fermented foods: Fermented foods are rich in probiotics, which help your gut and immune system. They also have vitamins, minerals, and enzymes.

DIY Sauerkraut, Yogurt & Kefir — Step-by-Step

Basic steps for fermenting vegetables:

1. Clean and chop vegetables.
2. Make a brine solution (water and salt - see ratios below).
3. Submerge vegetables in the brine.
4. Use a weight to keep vegetables under the brine.
5. Cover the container with a cloth to allow airflow.
6. Store in a cool, dark place and check regularly.

Making homemade yogurt and kefir:

• Yogurt: Heat milk to 180°F and cool to 110°F. Add a yogurt starter and keep at 110°F for 6-12 hours.
• Kefir: Add kefir grains to milk and let it ferment at room temperature for 24-48 hours. Strain the grains and enjoy.

Fermentation Storage: Keeping Batches Fresh & Safe

Ensuring safe fermentation: Use clean equipment and good ingredients. Watch the process and throw out any batches with bad smells or mold.

Storing fermented foods: Store fermented foods in the fridge to slow down fermentation and keep them fresh. Use airtight containers.

FREEZING

Freezing: The Easiest Way to Preserve Food

Why Freezing Protects Flavor & Freshness

Benefits of freezing food: Freezing is easy and keeps food tasting fresh. It helps you store seasonal produce, bulk buys, and leftovers, reducing waste.

Types of foods suitable for freezing: Most foods can be frozen, like fruits, vegetables, meats, seafood, dairy, and prepared meals. Some foods, like lettuce, don't freeze well.

Having noted that seafood can be frozen, it's best not to do that IF you are thinking of dehydrating it later. 

Freezing Like a Pro: Blanching, Packing & Storage Hacks

Blanching vegetables before freezing: Blanching means boiling vegetables briefly and then cooling them in ice water. This keeps their color, texture, and nutrients.

Proper packaging and storage tips:

• Use airtight containers or freezer bags to prevent freezer burn.
• Label packages with the date and contents.
• Arrange items in a single layer to freeze quickly.
• Keep the freezer at 0°F or lower.

Safe Thawing: Best Ways to Use Frozen Food

Safe thawing methods: Thaw frozen foods in the fridge, under cold water, or in the microwave. Don't thaw at room temperature to avoid bacteria.

Best practices for using frozen foods: Use frozen foods within their recommended times for best quality. Add them to recipes directly from the freezer or after thawing.

PICKLING

Pickling: Tangy Flavor Meets Long Shelf Life

What Is Pickling and Why Use It?

What is pickling? Pickling means soaking food in vinegar or salty water. This keeps the food fresh and adds a tangy flavor.

Benefits of pickling: Pickling makes vegetables and fruits taste great and keeps their nutrients. It also provides probiotics.

Quick Pickles vs. Traditional Pickles — Which Works Best?

Quick pickling vs. traditional pickling:

• Quick pickling: Soaking food in vinegar for a short time, usually a few hours to a few days. Good for small batches.
• Traditional pickling: Fermenting food in brine for several weeks. This gives deeper flavors and longer storage.

Step-by-step guide to pickling vegetables:

1. Clean and chop vegetables.
2. Make a pickling solution (vinegar, water, salt, and spices - see ratios below).
3. Pack vegetables into sterilized jars.
4. Pour the pickling solution over the vegetables.
