TV personalities and chefs The Estate Of Anthony Bourdain and Éric Ripert have teamed up with American retail company Williams-Sonoma, to launch the exclusive Good & Evil Chocolate Bar.

The bars, made from 72% premium Fair Trade organic cacao beans, can be bought via the company's website, and Bourdain commented 'A little guilt, in appropriate amounts, can only make one's simple pleasures better. This bar contains the perfect blend of good ingredients and evil intent. Enjoy it at your peril. You'll be back for more'.
