They are classified as beef offal. Sourced from bulls and calves. The tradition of eating penises derived from ancient Chinese medicine. According to it, eating penises used to be the same as swallowing potency pills is today. Thanks to the increasing level of “yang” (masculinity, activity), they became the basis for preventive struggle with impotence and infertility. Based on this, Chinese people created traditional Chinese soup with a beef pizzle. The beef pizzle, as a highly respected specialty, deserves special treatment. Therefore, it is a soup base that stands alone. Neither other meats nor vegetable are added to the base. In order to reduce the characteristic smell, the beef penis is soaked in vinegar and then simmered approx. 2 hours. In China, skewers of beef penise are also popular. Apart from China, however, the beef pizzle is mainly used for the production of dog food, very valuable and rich in proteins.
