Great recipes, awful binding . I've reviewed this cookbook before from the point of view of the contents, for which I gave it 5 stars. I use this cookbook all the time and absolutely love it. Unfortunately, I use this cookbook all the time and the cheap glued binding has not held up. About half the pages have detached and I'm a few chapters away from having to pull the whole thing apart and put it in a three-ring binder. Interestingly, the same publisher used a sewn binding for the Babbo Cookbook, so I guess the gourmet recipes get the quality treatment. I would still recommend purchasing the cookbook for the wonderful preparations, but shame on the publisher for using such poor components on a book designed to be repeatedly opened and laid flat

Ex Output:
NEG
