5 reviews, all of them with a 4-star rating - it seems obvious that this is a very reliable cookbook. Also, it's huge, and you can find recipes for nearly every topic.
Personally, I do skip quite a few of them as many seem to contain pre-manufactured ingredients such as sauces and salad dressings. In fact, I've seen a recipe for a salad that contained a salad dressing - doesn't that defeat the purpose of cooking? I also check on things like sugar and fat content, as these sometimes are higher than I'm comfortable with. Both of these issues might be just cultural differences.
