Author and food stylist Fred Thompson says he didn't like waiting in line for the famous frozen hot chocolate at Serendipity 3 in New York City, so he decided to create his own recipe, featured in his book Hot Chocolate (Harvard Common Press, 2006). "Serendipity has published its 'secret recipe,' but you need a trip to Europe to buy all the chocolates," says Thompson, who divides his time between NYC and Raleigh, N.C. "My version makes shopping easier." Thompson recommends double-batching the base and storing it in the refrigerator. "I have yet to see the time when one was enough," he says.
