The practice of Tan Jiacai thick soup is a secret, and no one will know the practice of this soup except the chef in Tan Jiacai.

Speaking of "Tan Jiacai", I think of "Li Jia Cuisine". In addition to these two dishes, there are Duan Cai, Ren Cai and Wang Cai, all of which are private kitchens. However, the most famous ones are Li Jiacai and Tan Jiacai!

Private cuisine, as its name implies, is private cuisine. What you eat in someone else's house is the good food cooked by the host.

Private kitchens usually have no storefront signs, fixed menus and full-time waiters, but the cooking techniques of these dishes are often ancestral, with unique flavor and limited supply, which can't be eaten in restaurants on the market.

No one should know the recipe except the descendants of private kitchens. Even if there is, it is fabricated or imitated. Of course, it's not a private kitchen anymore. o(∩_∩)o ...
