Storing steak long term without electricity requires alternative methods to preserve the meat. Here's a step-by-step summary on how to prep and store steak in such circumstances:

1. Choose fresh steak: Start with fresh, high-quality cuts of steak. Ensure the meat is properly handled and refrigerated before beginning the preservation process.

2. Dry-age the steak: Dry-aging helps enhance the flavor and tenderness of the meat. Hang the steak in a cool, well-ventilated area with low humidity, ideally around 34-38°F (1-3°C). Let it age for a specific period, depending on your preference and the thickness of the steak (e.g., 7-21 days). Check for any signs of spoilage during the process.

3. Butcher and portion the steak: Once dry-aged, if needed, butcher the steak into smaller portions suitable for your consumption needs. Remove excess fat and trim the meat as desired.

4. Wrap with butcher paper: Wrap each portion tightly with butcher paper, making sure to cover the entire surface of the steak. Secure the paper with tape or twine. This helps protect the meat from air exposure and prevents freezer burn.

5. Label and date the packages: Use a marker to label each package with the type of steak and the date it was wrapped. This will help you keep track of the storage time and identify different cuts later on.

6. Store in a cool environment: Find a cool and dark place with a stable temperature, ideally between 34-38°F (1-3°C). Options may include a basement, cellar, root cellar, or an insulated outdoor storage container. Ensure the storage area remains consistently cool and doesn't experience extreme temperature fluctuations.

7. Check periodically for spoilage: Regularly inspect the stored steaks for any signs of spoilage, such as an off odor, unusual discoloration, or excessive moisture. Remove and discard any steak that shows signs of spoilage.

8. Use within the recommended storage time: While the exact storage time may vary depending on various factors, such as the initial freshness and the conditions of storage, aim to use the steak within a few weeks to a couple of months for the best quality.

By following these steps, you can prep and store steak long term without electricity. Remember to prioritize food safety, and if you have any doubts about the freshness or safety of the meat, it's best to err on the side of caution and discard it.
