Matisse, Picasso, van Gogh...Payard? We'll swear that Payard Chocolate's creations are so beautiful, you almost don't want to take a bite, except you can't resist. Hand-sculpted and filled with liqueur, fruit or nuts, each sumptuous piece is named for a famous artist. The Degas, "painted" with coffee beans and packed with luscious coffee ganache (smooth chocolate and cream), is our idea of a masterpiece.   When Chef Payard wants to make a chocolate treat, what recipes does he turn to? Take a look at some of his favorites!
