Long Fusilli with Potatoes and Haricots Verts in Lemon Sauce
Lemon, grated cheese, and cooking water make up the remarkably simple sauce for this pasta. Baby fingerling potatoes in different colors look great, but any small boiling potatoes will taste good -- just cut them into quarters if need be.
Follow these steps when you cook the pasta for this dish: Bring a large pot of water (6 quarts) to a boil -- you want enough water so the pasta can move around. Season the water with 1/4 cup coarse salt. (The water should be well seasoned; think "salty like the sea.") Cook 1 pound of pasta until al dente. Drain, reserving at least 2 cups cooking water. The pasta releases starch as it cooks, and the starchy water is essential to the sauce.
