@Giverny - Could consideration be given to either/or dividing the book into its sections; starters, main courses, desserts, snacks, or whatever? That way, people like me who don't snack or do desserts, can download the relevant sections, and those who want it all can download them over a few sessions or days? It might also make the background re-packaging relatively simple?
Curiously, I can't find the book on the site this morning.
Just a thought.
