I pre-ordered this book on the basis of a wonderful recipe of Ms. Nathan's which was the basis of a blog entry on the Wednesday Chef. I made the cake and absolutely loved it. When the book came, I found the version of the recipe (blueberries instead of cranberries) and compared it to the one I had made--it didn't compute at all. As far as I can figure, the proportions of dry to wet ingredients are off by a lot.
People rave about Ms. Nathan's food and that cake I made was wonderful. So I don't want to give up on the book entirely, and there are a number of recipes which I have on my "to make" list.
I've noticed this before--a chef takes a recipe which is very successful and which is generally made in a large quantity and revises it to suit the "home cook" and in a much smaller quantity. And it doesn't work. There's a Nutella Swirl Cake which is fabulous, but only after one reworks the ingredients list and the instructions--same thing as the Nathan cake.
