I think the highest level of a chef is to make everyone enjoy the food he makes.
For example, he can make dishes taste like meat, meat can taste like vegetables, he can make one dish taste like ten dishes, he can also make ten dishes taste like one dish, and he can even affect people's emotions.
.
This is the highest level of a chef.
Well, I think you can refer to "The Magic Chef of Ice and Fire" by the Third Young Master of the Tang family, that's it.
