Today, EVERYDAY FOOD presents casual dinner-party dishes that will impress guests any time of year. For the main course, Lucinda prepares a succulent and moist brandy ham glazed with brown sugar, mustard and, of course, brandy. The impressive but easy-to-make side dish is crisp potato roast. Today's "Have You Tried?" ingredient is chorizo; Anna shows how this dry Spanish sausage adds zing to a whole range of dishes, from breakfast to dinner. She prepares a simple and delicious pan-fried chorizo with sherry vinegar that makes the perfect appetizer. Sarah's seafood and chicken paella has something for everyone: shrimp, mussels, chicken and spicy chorizo, all tucked into a bed of saffron rice. Finally, a great dinner deserves a great dessert. John's warm chocolate pudding cakes with caramel sauce will send dinner guests home with smiles on their faces.
