The good news about chocolate just keeps melting in. This week, the august European Food Safety Authority (EFSA) gave the nod to Barry Callebaut, the world’s largest chocolate manufacturer, allowing them to claim that cocoa flavanols are good for blood circulation. I wish I could fly to Zurich, the headquarters of Barry Callebaut, to offer my personal congratulations, and to ask for as many samples as they are willing to hand out to a weary traveler. And as long as I was there, I’d also conduct a personal investigation to try to figure out what it is about the Swiss that makes them the world’s whizzes in a trio of seemingly disconnected enterprises: precision watches, secret bank accounts, and divine chocolate. Perhaps the secret link is hidden away in a dossier in a Swiss bank vault, surrounded by priceless specimens of chocolate.
