I have no experience with LaTeX, but if you setup a GH repo for the open-source chapters and privately send me a scan of the book, I and/or others could submit PR requests on a chapter-by-chapter basis with some plaintext transcriptions. Someone could mark up the recipe sections to LaTeX from there.
Ditto on this! LaTex also isn't too terribly difficult, so it might be possible to get 90% the way there just by copying what's been done for the first chapters already, and then @chrissnell can do the fine formatting how he'd like it to look.
