To prepare the ragout, put the chopped onion in a pan with the bacon and 4 tablespoons of olive oil and brown them on low heat. Add all the minced meat and fry over a high heat. Once the meat has reached a uniform color, drizzle with the wine and let it evaporate. Add a laurel leaf, the cinnamon, a few peppercorns, salt (or stock) and the tomato sauce. If the tomato sauce is too thick, add a little bit of hot water. Cook over moderate heat for about 60 minutes.
Form with the rice a ball (about the size of a tennis ball) and dig in it a central depression in which you are going to put a teaspoon of filling; then close the “ball”. Create as many balls as possible with rice you have. With the flour and a little bit of water make a smooth batter, dense enough to cover the arancina, then dust it with the bread crumbs and fry it in hot oil. Note: make sure each arancina is well compacted after breading.
