Jacques and Claudine revive a classic country tradition: the relaxed, sit-down, midday luncheon. For starters, there's a classic Parsleyed Ham, served with a tangy Rémoulade Sauce. Linguine with Clam Sauce is an ideal choice for entertaining, and Jacques dresses it up with a rainbow of colorful spring vegetables. And for dessert, Plums Poached in Cabernet Sauvignon and homemade Plum Sherbet are served over a surprisingly easy Cinnamon-Lemon Cake.
