Whatever cookbook you choose, remember, recipes are a starting point, not the goal. Learn the techniques, and how to use the tools of cooking from the books. Real cooking comes when you start experimenting with flavors and techniques to create your own masterpieces.
It is absolutely true that the first time I roasted a chicken on my Webber Grill, I followed a recipe. It gave me technique. I was able to take what I learned from grilling that chicken, and transfer it to roasting turkeys both in the oven, and on the grill. They come out perfect because I was able to learn how meat reacts to heat, and to different kinds of heat. That's what you use your cookbook for. It is a teaching tool.
And don't be afraid to alter the recipes. You will get the hang of it in no time. That's the lesson I try to teach in my blog.
