Instructions: Make the Meat Broth: Wash the bones, meat scraps, and vegetables thoroughly under cold running water. Place all of the bones, scraps, and vegetables in a large stockpot. Add enough cold water to cover by 3 to 4 inches. Partially cover the pot, and bring just to a boil over medium heat. As soon as water begins to bubble, reduce heat to low, and skim off all foam that has risen to the surface. Simmer gently for 3 hours. Season with salt during the last few minutes of simmering.

If you are planning to use the broth within a few hours, strain it through a fine-mesh strainer directly into another pot, and remove the fat that comes to the surface of the broth as it cools.

If the broth is for later use, strain it, divide it among several small containers, and place the containers in a bowl of ice water to cool completely. The broth can be kept in the refrigerator, in airtight containers, for up to 3 days or frozen for up to 2 months. Before using the broth, remove the fat that has solidified on the surface, and bring to a full boil. (

Makes about 2 quarts)

Make the ragu: Heat the oil and 2 tablespoons of the butter together in a medium saucepan over medium heat. As soon as butter begins to foam, add the minced vegetables. Cook, stirring occasionally, until vegetables have a nice golden color. Add the pancetta, and cook until lightly golden, about 5 minutes. Add the ground beef and pork, raise heat to high, and cook, stirring and breaking up meat with a wooden spoon, until meat and vegetables have a rich brown color and bottom of pan is glazed, 7 to 8 minutes.

Add the wine and cook, stirring, until almost all of it has evaporated. Season with salt and pepper. Dilute tomato paste in the 3 cups of meat broth. Stir into the ragu. As soon as liquid comes to a boil, reduce heat to low, partially cover pan, and simmer for about 2 hours, stirring and checking sauce every 20 minutes. The sauce should be thick, with an appealing nutty brown color, and just slightly liquid. Add a bit more broth or water if the sauce looks too dry.

Add the milk, partially cover, and simmer for 10 to 15 minutes longer. Taste, and adjust the seasoning. Turn off the heat.

Meanwhile, bring a large pot of salted water to a boil over high heat. Add the tagliatelle, and cook until pasta is tender but still firm to the bite. Drain the pasta, and place in a large heated bowl.

Add remaining 1 tablespoon butter, about two thirds of the sauce, and a small handful of the cheese. Toss quickly until pasta and sauce are well combined. Add more sauce if needed. Serve at once, with the cheese.

This recipe yields 4 to 6 servings.

Comments: Tagliatelle is the northern Italian term for fettuccine, a favorite type of pasta whose width can vary from 1/8 to 1/2 inch.
