REFLEXIONES DE LOS CREADORES 
Gourmet_DAO
Gourmet_DAO Of course, for such an interesting and huge material, someone else is needed, but as long as it is not there, I will try to at least draw attention to this topic.
Another thing is how the author succeeds or fails to present this material.
The author wanted to note that English is his third language, so grammatical errors are inevitable. So do not rush the reader immediately rush slippers. I hope for criticism but in a positive way.
