For the people who call this novel trash just because of the title "Maverick Chef" is really a narrow-minded person. You can read in the synopsis that "Bai Lu grew up in a mysterious prison, where he learnt many interesting abilities." He grew up in a PRISON! with different kinds of people that he encountered living there is enough for him to have various skills and logically can include it in the story.
A person in real life can have a lot of experience and skills in various things and jobs especially if you're not a well-off person, so don't judge this book if the story is not a proper gourmet novel. This kind of story makes it more interesting because it's not just all about cooking, it also shows the background of MC.
