This is the classic Italian meat sauce, with an official recipe approved by the Accademia Italiana della Cucina and recorded with the Bologna Chamber of Commerce. The recipe gets updated every few generations to account for the changing availability of ingredients, and importantly, to note which popular variations that have arisen are incompatible with the Accademia's focus on authenticity and quality (for example, using cream instead of milk, or brandy instead of dry wine).
This is from the most recent edition, recorded in 2023.
