When choosing seafood that's caught responsibly and low in mercury, here's a good rule of thumb: the smaller, the better. Here are a few of our favorite sustainable seafood recipes. Pasta with Sardine Cream Sauce Look for wild-caught sardines from the Pacific Ocean when making this simple pasta dish. Mussels with Thai Seasonings Coconut milk, lime juice, and green curry paste lend Far East flavors to this quick-cooking dish. Clam Chowder with Bacon Thomas Keller's version of the New England classic is made with applewood-smoked slab bacon and sweet littleneck or Manila clams. Baked Spiced Herring Herrings have a rich, meaty flavor that's perfect for roasting, as in this easy, aromatic recipe from James Beard.
