This soup is very typical of the light and delicate cooking of Emilia-Romagna; it is a simple rich meat broth thickened with ribbons of[ a Parmesan paste. Though traditionally made with a special perforated and disc-shaped kitchen tool, a food mill will work just as well.]
- 6 to 8 servings
In a large saucepan, bring the beef broth to a slow boil. In a bowl, combine 1 cup of the Parmesan cheese, the bread crumbs, nutmeg and lemon zest and juice and make a well in the center. Add the eggs to the well and slowly incorporate into the dry ingredients, until it comes together and resembles cooked polenta. (If the mixture is too thin, add a bit more grated cheese and bread crumbs.)
Transfer the cheese mixture to a food mill fitted with the large die. Hold the food mill as high above the steaming broth as possible, and turn the handle so that the Parmesan mixture is forced through the mill into the slowly boiling broth. Cook for 1 to 2 minutes without stirring. Remove from the heat and let sit 5 minutes. Ladle into soup bowls and top each with a sprinkling of fresh herbs and the remaining grated cheese. Serve immediately.
