While I have been duped, about it being his"new" book,the file does contain 140 pages of his recipes. He admits to it on his web site.
Jamie has the following disclaimer on his website:
Thank you to everyone who has emailed us about the hoax book that has been circling the globe via the internet. Just so you know, it's not my new book but a bunch of recipes that have been taken from the website in the US. Not good either way though.
I have opened the file and it looks real enough. If anyone would like a copy of these recipes,my offer still stands.
