After evenly chopping the onion, garlic, celery and carrot sauté in a saucepan or pot gently for 10-15 min. in 2-3 tablespoons of olive oil, salt and pepper,
remove and Brown the ground pork, add the beef and finally the veal on high heat
Once the meat has browned, salt and pepper, and after evenly chopping the onion, garlic, celery and carrot, add them. Add a glass of good dry red wine, and once evaporated
then the peeled, seeded and diced tomatoes, stir and lower the heat.
cook for a half hour then add the milk,
Cook slowly for 1-2 hours, adding meat broth or water as needed. then another 1-2 hours. then another 1-2 hours. then another 1-2 hours.... some people cook the thing for days, quite literally. But 3-4 hours should be enough for most.
Note... you can mix and match ground or hand-pureed (a sharp knife or two, attention and patience is required) meats and flavor as you will, (it makes a difference and a traditionalist might cringe understandably but someone had to actually, you know, take the time to cook the stuff,) remove a thing or add another, use sweet onion or scallion, lamb, fowl, kangaroo, buffalo... even reptile.
The whole alchemy is tied to gently cooking the stuff low and slow until it all blends into a forkful of delight. Anyway...boil the tagliatelle in abundant salted water:
don't overcook the pasta
Once ready, actually a little before, out it goes. And when ready, ladle the ragout over the noodles and add freshly grated Parmigiano Reggiano. Serve with a medium structured red wine. And wonder why anyone would eat anything else...except, maybe, a stracotto - which will be for the next JJ recipe....
