My all-time favorite chocolate cookbook is Luscious Chocolate Desserts by Lori Longbotham. It also features beautiful photography by William Meppem. The recipes are easy to follow and are absolutely divine. Also, she includes a brief history of chocolate, the process to make chocolate, as well as the different forms of chocolate. Being a chocolate addict and all, I found it very interesting. FYI, did you know in the 1700s, Italian doctors used chocolate in medicines?
The Chocolate Chip Gingerbread Cake and the French Chocolate Macaroons are my two very favorites. Some other great recipes are: The Original Chocolate Decadence; Chocolate-Hazelnut Spread on Toast with Nectarines; Chocolate, Dried Cherry, and Pistachio Bread and Butter Pudding; Black Velvet Chocolate Mousse; Katherine Hepburn's Brownies; Ganache-Filled Brown Sugar Bars; etc, etc. Anyone hungry yet? I wouldn't blame you, I did mention chocolate a total of 14 times.
