Established in 1996, Scharffen Berger has become America"s preeminent maker of cooking chocolate. Essence of Chocolate, by the firm"s founders and food writer Susie Heller, offers more than 100 recipes for a broad selection of delights like Chocolate Pudding Cakes, Chocolate Marbled Gingerbread, Cocoa Caramel Panna Cotta, and Chocolate Chunk Cheesecake, as well as savory edibles made with chocolate like Tortilla Soup and Chile-Marinated Flank Steak. Unusual recipes also include the likes of Chocolate Chunk Challah and TKOs, a homemade version of Oreos that leaves those favorites on the supermarket shelf. Arranged by chocolate intensity, the recipes come from the company"s files and from chefs including Flo Braker, Jim Dodge, Thomas Keller, and Stephanie Hersh. Although the formulas vary in difficulty, most are within the range of all cooks interested in making something terrific. Readers should note, however, that the recipes require chocolate with specific cocoa-solids contents--62% semisweet, for example--that may be difficult to find. Most cooks will know, however, that one high-quality chocolate of similar cocoa content can usually replace another. With narrative sections in which Steinberg and Scharffenberger trace (at perhaps excessive length) their career trajectories, interesting asides such as "Bread and Chocolate," lots of chocolate lore, and a good primer on how chocolate is manufactured--plus color photos--the book makes a happy addition to the chocolate lovers" kitchen library. --Arthur Boehm
