At first glance, Chris Cosentino seems like a madman of the culinary arts. A dedicated proponent of "head to tail" dining - in which you literally feast on every part of the animal - his food may seem a little crazy too, at first. But his Grilled Beef Heart, Fried Cow Testicles and Chocolate Blood Pudding are delectable treats for the palate. And his Incanto Restaurant in San Francisco has caught the attention of many celebrated peers of the culinary world - like Jamie Oliver and Anthony Bourdain. Chris credits his admitted ADD/ADHD for his vivid imagination.
