MARCELLA HAZAN'S LASAGNA

Steps:

• Bechamel Sauce: (make just before you need it, not ahead of time) Put milk in a saucepan, turn heat to medium, and bring to the verge of a boil. While heating milk, put butter in a heavy-bottomed saucepan and turn heat to low. When melted, add the flour and stir with a wooden spoon. Cook, while stirring constantly, for about 2 min. Do not allow flour to color. Remove from heat. Add the hot milk to the flour/butter mixture, no more than 2 Tb. at a time. Stir steadily and thoroughly. Once the first 2 Tb. have been incorporated, repeat this process 2 Tb. at a time until 1/2 c. has been incorporated. Then, you can begin adding milk 1/2 c. at a time until all incorporated. Place the pan over low heat, add salt, and cook, stirring constantly until sauce is like thickened (like the consistency of sour cream). When done, you can keep warm on top of a double boiler and remove film if one forms on top. Lasagna: Preheat oven to 400. Prepare lasagna noodles. Thickly smear the bottom of your lasagna pan with butter and 1 Tb. of bechamel. Line the bottom of pan with one layer of noodles. Combine the bolognese and bechamel sauces and spread a coating on the pasta. Sprinkle some grated Parmesan, then add another layer of noodles. Repeat the procedure of spreading sauce and Parmesan and noodles. Leave enough sauce to spread a thin layer on top at the end. Sprinkle with Parmesan and dot with butter. (This can be made up to 2 days in advance and refrigerated.) Bake on top rack until golden crust forms on top, about 10 or 15 minutes. Remove from oven and allow to settle for 10 min. before serving.
