The best way to cook air-dried beef is to cook it slowly. Place the meat in a pot of water, add some onion and garlic, and cook it over low heat for a few hours. This will tenderize the beef while maintaining its texture and nutritional value.
If you want to add flavor to your air-dried beef, consider using some spices. For example, you can add some star anise, cinnamon and peppercorns to give the meat more flavor. You can also add some soy sauce or bean paste during the cooking process to add more flavor to it.
Lastly, remember to let the meat dry for a while after cooking. This will make the meat more flavorful and will reduce the amount of remaining moisture. You can hang the meat in a ventilated area and let it dry naturally for a while.
In short, cooking air-dried beef requires some patience and skill, but if you take the right approach, you can enjoy the unique taste and flavor of this delicious meat.
