Recipe(tried): Authentic Italian Spaghetti Bolognaise recipe

This isn't quite traditional because I add the garlic and rosemary, two of my favorite flavors. If you're feeling rich you can add dried Porcini mushrooms that have been soaked and chopped when you cook the vegetables and also strain the soaking water into the sauce before simmering. Sometimes we get wild ones growing near here and then dry our own but haven't had much luck the past few years.

cup red wine or imported Marsala
