Any recipe of Giada's, if followed as written will work.
The other day I saw a rerun of Everyday Italian in which Giada makes her version of an Oreo. When I first saw the episode I thought I would try it. However, when I looked at the reviews of the recipe, they were not good. Not good at all. Lots of problems with the recipe, many people did not like the texture, and some said the cookies were too buttery. So, I passed on making them. Upon seeing the episode again, I decided, to try it anyway. But, against my better judgment, I followed the changes the reviewers suggested.
I have no clue who these people are, but their suggested changes resulted in a shortbread like cookie, not at all what it was supposed to be. These were dry and crumbly. Not horrible, but not at all what it was supposed to be. I scraped that batch and started over, following Giada's recipe. And of course, it worked fine. I experienced none of the issues these reviewers encountered. The cookies did not all spread together, they were not hard to get off the cookie sheet, they are not too buttery. I don't know who these people are, but I would be terrified to try their cooking if they think their changes helped this recipe.
Moral of the story: Giada is right. If you want to make one of her recipes, she has laid it out for you. Just do what she says and it will work. You want to tweek the seasoning to your palate, go ahead, but don't totally change the recipe if you want to make what she makes.
