I don’t know about you, but I consider studio photo as one of the most complicated photography techniques (possibly with underwater photos while diving). But in the middle of this general context, photographing dishes to illustrate a book seems to be one of the most difficult specialties.
I will not detail the technique, but I want to invite you to visit a web site which totally mastered it: Habeas Brulée. They publish quite tasteful recipes, of course, but the work they put in the pictures is impressive and classify them as real pros.
If you want, you could draw some inspiration from the variety and quality of framing and lighting.
