Would you be inclined to buy a cookbook devoted to burgers, fondue or toast? I wouldn't. None of those things are all that challenging to make in the first place. A whole book on grilled cheese sandwiches? Gimme a break.
Cookbooks on single subjects have to be something special to catch my eye. They have to be varied, cover more than just one meal, and they should intrigue me to try something new and way out of the ordinary.
Pomegranates: 70 Celebratory Recipes is just such a book. Kleinberg's book includes recipes appropriate for breakfast, lunch, dinner and dessert. Not to mention beverages. Pomegranate juice and syrup is all over the place.
No wonder as it is filled with antioxidants, used in many different cuisines and amazingly versatile. You can use the jewel-like seeds or the juice in recipes that are sweet or savory.
