Prep:
Peel the carrots and onion. CHOP the carrot, onion and celery. Melt the butter in a large saucepan and add the olive oil.
Sauté the carrots, onion, and celery over medium heat. When the onion begins to brown, add the ground meats. Brown the meat on all sides. Add the chicken livers and cook for an additional 2 minutes. Add the wine and cook until it evaporates. Stir in the tomato paste. Add the nutmeg, salt and pepper. Add the stock and bring the mixture to a boil. Reduce the heat and cover the pot. Simmer for 2 hours, stirring occasionally. After 2 hours, if the sauce is too thin, simmer uncovered for another 10-15 minutes. The sauce should be quite thick. Remove it from the heat and stir in the cream.
Prepare the pasta:
Bring a large pasta pot of lightly-salted water to a boil. Cook the pasta, according to instruction. Drain the pasta and mix in the ragu. Sprinkle with GRATED Parmesan cheese and serve hot.
