Pass the previously cooked meats (braised and roasted) through a meat grinder.
Gather them in a bowl and add the brain, eggs, breadcrumbs, and 40 grams of Grana cheese.
Mix everything and season with salt, nutmeg, cloves, and pepper.
Place flour on a work surface to form a fountain, crack the eggs into the center.
Mix and knead the ingredients until a homogeneous dough forms.
Roll out the dough with a rolling pin until you get a thin sheet.
Place the filling on half of the sheet in small mounds at equal distances. Press around the mounds with your fingers to seal the pasta.
Cut out marubini shaping them into round shapes. If you do not have the proper tool, you can use an inverted glass.
Cook the marubini in the broth and serve them very hot with a sprinkle of the remaining Grana cheese.
