The white part of the fried beef with kitchen smoke is embroidered cocci. Embroidered cocci is a kind of nutrient-rich fungus, which looks like hydrangea, also known as "Saussurea involucrata" and tastes very delicious. In the cooking process, Streptococcus embroidered absorbed the soup and taste of beef, making it richer in taste and stronger in flavor.
