Salting, also known as curing, is one of the oldest and most reliable methods of meat preservation. By coating meat with salt, moisture is drawn out, creating an environment where bacteria cannot thrive. This method not only extends the shelf life of meat but also enhances its flavor.

• How it works: Salt dehydrates the meat and inhibits microbial growth, preventing spoilage.
• Modern application: Curing salts, such as pink curing salt, are often used to preserve meats like bacon or sausages.
• Historical example: Prosciutto from Italy is a classic example of cured meat.

Practical Example: Curing Meat at Home

What you need:

• 1 kg of pork belly or beef cut
• 50 g of kosher salt (non-iodized)
• 2.5 g of pink curing salt (optional, for long-term preservation)
• 20 g of sugar (optional, to balance flavor)
• Your choice of spices: black pepper, garlic powder, or smoked paprika

Steps:

1. Prepare the meat: Trim any excess fat and pat the meat dry with a paper towel.
2. Apply the salt mix: Mix the kosher salt, curing salt, sugar, and spices in a bowl. Generously rub the mixture onto the meat, ensuring every surface is well coated.
3. Refrigerate: Place the meat in a resealable bag or wrap it tightly with plastic wrap. Store it in the refrigerator for 5-7 days, flipping it daily to ensure even curing.
4. Rinse and dry: After curing, rinse the meat under cold water to remove excess salt. Pat it dry with a paper towel and let it air-dry for a few hours.
5. Optional drying: For long-term preservation, hang the meat in a cool, ventilated space for 1-2 weeks to allow further drying and flavor development.

Result: The cured meat will be ready to slice and enjoy as a savory addition to meals or snacks. Properly cured meat can last for months when stored in a cool, dry place.

2. Drying and Sun-Drying

Drying meat is one of the simplest and most effective ways to preserve it, as it removes moisture that bacteria need to grow. In warmer climates, sun-drying has been a traditional practice, while in cooler areas, air-drying in well-ventilated spaces has been preferred for centuries.

• How it works: Thinly sliced meat is exposed to air or sunlight until it becomes dry and hard, preventing spoilage.
• Modern application: Jerky, made from beef, chicken, or even game meat, is a popular example of dried meat enjoyed globally.
• Historical example: Charque or carne seca from South America was a staple for communities in tropical climates, offering a reliable protein source.

Practical Example: Sun-Drying Meat at Home

What you need:

• 1 kg of lean beef (fat is removed to avoid spoilage)
• 1 tbsp of salt
• Optional: 1 tsp of spices (cayenne pepper, garlic powder, or smoked paprika)
• A drying rack or string to hang the meat

Steps:

1. Prepare the meat: Slice the beef into thin strips, about 1 cm thick and 10-15 cm long. Ensure all pieces are of uniform size for even drying.
2. Season the meat: Rub the salt (and spices, if desired) evenly onto the strips. Let the meat sit for 30 minutes to allow the salt to penetrate.
3. Set up the drying area: Choose a sunny, well-ventilated spot. Place the meat on a drying rack or hang it using string. Protect it from flies and insects by covering it with a fine mesh or net.
4. Sun-dry the meat: Allow the meat to dry in direct sunlight for 2-3 days. Turn the strips occasionally to ensure even drying. The meat is ready when it becomes firm and slightly brittle.
5. Store the dried meat: Store the dried strips in an airtight container or vacuum-sealed bag. Keep them in a cool, dry place for up to several months.

Result: You’ll have a batch of naturally preserved, protein-rich dried meat perfect for snacking or cooking. Sun-drying not only enhances the shelf life of meat but also intensifies its flavor.

3. Smoking

Smoking is a time-tested method that combines drying with the natural antibacterial properties of wood smoke. This technique not only preserves meat but also infuses it with rich, smoky flavors, making it a favorite across cultures.

• How it works: Meat is exposed to smoke from burning wood, which dehydrates it while coating the surface with antimicrobial compounds that prevent bacterial growth.
• Modern application: Smoked sausages, hams, and fish remain widely consumed delicacies around the world.
• Historical example: In northern Europe, smoking was essential for preserving meats during cold winters, ensuring communities had a reliable protein source.

Practical Example: Smoking Meat at Home

What you need:

• 1 kg of meat (beef, pork, or fish works well)
• 1 tbsp of salt (for seasoning and pre-curing)
• Optional: Spices or a marinade for added flavor
• A smoker or a makeshift setup with a grill and a lid
• Hardwood chips (oak, hickory, or applewood for flavor)

Steps:

1. Prepare the meat: Slice the meat into manageable pieces, about 2-3 cm thick. Rub the salt (and any spices or marinade) evenly over the meat. Let it sit for at least 30 minutes to absorb the seasoning.
2. Set up the smoker: Use a dedicated smoker or create a makeshift one using a grill with a lid. Place the hardwood chips in the smoker or directly on the hot coals to generate smoke.
3. Start smoking: Arrange the meat on the racks, ensuring the pieces don’t overlap. Close the smoker or grill lid to trap the smoke and maintain a steady temperature between 70-90°C (160-200°F).
4. Smoke the meat: Allow the meat to smoke for 4-6 hours, depending on the thickness. For safety, ensure the internal temperature of the meat reaches 65-70°C (150-160°F).
5. Cool and store: Once the smoking is complete, let the meat cool to room temperature. Store it in an airtight container or vacuum-sealed bag in a cool, dry place.

Result: Smoked meat can last several weeks to months, depending on how it’s stored. The smoky flavor and enhanced texture make it a delicious addition to meals or snacks.
