As a chef, you must have a certain foundation. Then you should actually learn quickly. You can watch them operate first, and then make a note or something. In the process of reading, if there is anything unclear, you can actually ask the chef what materials are used, and then ask some specific details. Then taste their cooking. Then I will actually do it a few times, and then I will taste my own cooking. Of course, everyone's cooking tastes a little different, but the purpose is just to taste good, right? So as long as the taste is close, and then the taste is great, it is actually ok. Then, if you still feel unfamiliar with the operation, you can also see how the previous chef operated. Then practice more by yourself.
