Steamed Mussels With Lemon-Saffron Sauce

The name for this beautiful Bordelais dish is mouclade. Use small mussels to approximate the tiny, sweet variety cultivated just off the coast north of Bordeaux. What to drink: Baron Philippe de Rothschild 2000 Mouton Cadet Blanc. From Bon Appetit, October 2002.
