It's festive fun with the Barefoot Contessa who is throwing a dazzling holiday dinner party for friends. A luxurious seafood gratin of lobster, halibut and plump pink shrimp in a golden saffron sauce is served. To follow, there's a creamy pumpkin mousse then spicy mulled wine and festive s'mores stuffed with French chocolate bark round a burning brazier in the garden.
