James Beard

This quote seems to ring true from someone who knows about food:

A steaming cup of hot chocolate with buttered toast is surely one of the most heart warming, body warming, and taste-satisfying combinations known to man.
--James Beard

James Beard operated a cooking school out of his apartment in New York, wrote dozens of books on cooking and food, and hundreds of articles on food for many different magazines. He is recognized as the father of American gastronomy

The hot chocolate he was talking about was made with just two simple ingredients, pure dark chocolate and creamy milk.
