Typically, a ragù is started by first cooking the "soffritto" (onion, in this case) before adding the meat. If, like us, you live in a country where meat generally holds more water, we recommend starting with the meat so that it has some time to sweat and brown before adding the soffritto.
In a large, heavy pot (we recommend terracotta or a Dutch oven if available), melt the lard over medium/high heat. Add all of the meat in; don't be afraid to crowd the pot. Turning and mixing the pieces often, cook the meat until browned on all sides.
You can add the onion directly into the meat, but for best results remove the meat from the pot with tongs and set aside so that the onion can cook evenly.
Add the onion and fry in the lard for a minute or two, then place the meat back into the pot, along with a handful of fresh basil. Season with salt/pepper to taste. Next, add the wine and bring to a simmer. Cook for 15 to 20 minutes, until the alcohol has burned off and the wine has reduced a little bit.
Stir in the tomato paste and add the tomato passata. Add a few generous pinches of salt. Partially cover the pot and bring to a gentle simmer. Stir occasionally and cook for 2 to 3 hours, until the meat is very tender and almost falling off the bone.
Using tongs, remove the meat from the sauce and set aside for later. Bring the sauce to a simmer again, partially covered, and cook for a further 1 to 2 hours, until you reach a consistency thick enough to your liking. You can always add warm water and continue to cook for longer, developing the flavors even further! As the ragù nears completion, taste it and add salt as necessary.
The ragù is done! It can be refrigerated for a few days or frozen for longer storage.
If you plan on serving your ragù with pasta, followed by the meat as a second course:
Add the meat back into the finished sauce over low heat so that it can reheat and stay moist. Cook and drain your pasta, as directed. Place it back in its pot and ladle in enough ragù sauce to fully coat the pasta. Stir over medium/high heat for 1-2 minutes. Serve immediately, topped with extra ragù and grated Parmigiano or pecorino cheese.
Keep the meat warm in the sauce until everyone has finished the first course, then serve it. Buon appetito!
