For the semolina pie recipe, prepare the semolina polenta: bring the milk to a boil with a pinch of salt, then add the semolina all at once, stirring vigorously to avoid the formation of lumps: cook, over heat moderate, for about 20 ', then remove the polenta from the heat and incorporate the egg yolks, butter and a grated nutmeg. Turn out the dough into a rectangular pan and level it well. Let it cool. Meanwhile, prepare the sauce: chop the onion and let it dry in 3 tablespoons of oil. Add the sausage, deprived of the skin and crumbled; let it brown, then add the tomato pulp. Season the sauce with a clove and a pinch of salt. Cover and cook over medium heat for about 30 minutes. Whip the pie: cut the semolina polenta into 1 cm thick slices. Reduce the fontina into thin slices. Grease a baking dish that can also go to the table and place a layer of polenta on the bottom. Continue with part of the sauce, slices of cheese and a little parmesan, then continue until the ingredients are used up: the last layer will be of polenta covered with sauce, infiocchettata of butter and sprinkled with Parmesan. Pass the pie in the oven already heated to 200 for about 25 ', or for the time necessary to form a crispy crust. Serve warm.
