Fleischsaftgarung is a method of fresh meat that is cooked only in its own meat juice in a vacuum - just like in the kitchen. The meat juice is a nutrient-rich liquid that contains proteins, creatine and iron.
Dry food is created during a long cooking time in which the moisture of the meat juice is constantly reduced. During this process, the meat juice slowly condenses until the meat only has a small amount of residual moisture. Therefore, meat juice-cooked dry food is chewy-soft, which corresponds to the cooking level "Medium Well".
