A lot of Chris's offal-based recipes didn't appeal to me, but when I'm looking at cook books I'm more inclined to pick something up that is original. Besides, I'm sure Chris doesn't JUST cook with offal - he would have recipes to include the whole animal.
Personally I love beer, so I'd be checking his cookbook if he ever releases one. I'm sure many would agree with me. It's not to everyone's taste, I know - but it's more original than yet another home-recipe cookbook. I'll look at Julie's book when it comes out but unless she includes some recipes that don't fall under the home-cook recipe category I don't really see much point in purchasing it. It's a lovely idea for familys who are getting into cooking, but when i have kids, I'll already have many scrapbooks of recipes of my own to pass on - along with my mothers.
