Where is the authentic jelly? Where can I learn technology?

If you want to learn the technology of making bean jelly, I suggest you go to a professional chef school. Choosing a school from the aspects of school scale, teachers, equipment, accommodation and employment service can not only learn skills, but also have a promising job. It is recommended to go to a professional chef school to learn more comprehensively, and to learn technology, the hardware facilities of the school must be excellent. Only with more operations, practice makes perfect, and natural technology can be learned.
