1. In a saucepan melt 4 tablespoons butter & whisk in the flour. 2. When flour is completely incorporated, gradually pour in the milk, whisking constantly. Keep whisking until milk comes to a boil, then simmer for 2-3 minutes & remove it from the heat. 3. Stir in nutmeg, salt & pepper to taste, & add 1/3 of the cheese. 4. Let this sauce cool until just warm, then stir in the beaten egg yolks & set aside. 5. Bring a large pot of water to a boil, then add salt & pasta & cook for 2 MINUTES LESS than the package instructions indicate, so that the pasta is very al dente, as it will continue cooking in the oven. 6. Preheat oven to 375 degrees F & butter the inside of a 13"x9" baking dish. 7. When pasta is done, drain it & toss with the remaining 2 tablespoons of butter, then spread half of the pasta in the bottom of the baking dish. Pour half of the sauce over it & sprinkle half of the remaining cheese over that. Repeat layering with the remaining pasta, then the rest of the sauce & finally the cheese. 8. Place the baking dish on the oven's middle rack & bake 20-30 minutes or until golden. 9. Great when served warm or at room temperature with a fresh green salad. ---------------------------------------------------------------------------
