Cocoa beans were once used as currency by the Maya and Aztecs. Desage Chocolatier wraps their confections in gold foil as an homage to this. Desage has a long French tradition of chocolate making that dates back to the days of Napoleon. The brand existed in Paris for many years and then took their French traditions to Las Vegas in 1977. They take at least four days to make each individual bar. The chocolate is sold through Neiman Marcus and is also available online. A small box sells for $20.
