If you want to open a shop, medium and large baking and cake shops generally need to study for more than half a year, and both theory and practice need to be mastered and changed flexibly. The management knowledge of cake shops also needs to be understood. Private baking workshops generally take three months to study, and this short-term course can be adjusted in time according to the popular desserts needed by the market. But you must go to a professional school to study, and it is not recommended to go to a small institution.
