couverture
 n.— «Each week, Siegel and his five full-time employees use more than 1,000 pounds of couverture, the term for professional-grade chocolate. Siegel is a perfectionist. His aim is no less than “to produce the world’s finest chocolates.” The house chocolate, a 65 percent bittersweet, is made by blending couverture from several chocolate manufacturers.» —“Miniature works of art that can be eaten” by Catherine Nash Inside Bay Area (Oakland, California) June 13, 2006.
