The collection of recipes is a book. Copying that book may violate copyright. It is my understanding that making a different book with those same recipes does not violate copyright.
The entire poses copyright violation issue seems ridiculous to me. It's like laying claim to the XYZ coordinates on a plane. "My poses were the first to code the placement of a character into the scene at those coordinates! I demand attribution! I copyrighted that spot!"
Or "You can't sell a pose of the bending of a G8F figure's arm at that angle! That's MY pose!" It's preposterously silly.
