Wikipedia: Bolognese sauce
Bolognese sauce /bɒləˈnjeɪziː/, known in Italian as ragù alla bolognese [raˈɡu alla boloɲˈɲeːze; -eːse], ragù bolognese [raˈɡu boloɲˈɲeːze; -eːse], or simply ragù, is a meat-based sauce originating from Bologna, Italy, hence the name. In Italian cuisine, it is customarily used to dress “tagliatelle al ragù” and to prepare “lasagne alla bolognese”. In the absence of tagliatelle, it can also be used with other broad, flat pasta shapes, such as pappardelle or fettuccine. Genuine ragù alla bolognese is a slowly cooked sauce, and its preparation involves several techniques, including sweating, sautéing and braising. Ingredients include a characteristic soffritto of onion, celery and carrot, different types of minced or finely chopped beef, often alongside small amounts of fatty pork. White wine, milk, and a small amount of tomato concentrate or tomatoes are added, and the dish is then gently simmered at length to produce a thick sauce.
(...)
Outside Italy, the phrase “Bolognese sauce” often refers to a tomato-based sauce to which minced beef (or pork) has been added; such sauces typically bear less resemblance to ragù alla bolognese being more similar in fact to the ragù alla napoletana from the tomato-rich south of the country. Whereas in Italy ragù is not used with spaghetti, so-called “spaghetti bolognese” has become a popular dish in many other parts of the world.

Spaghetti bollock-knees and a movie tonight. I picked ‘Dark Skies’ to watch before seeing ‘Evil Dead’ was an option. They can’t be swayed…

Chic and stylish events on paper, these dinners have seen a huge progression from the bangers n mash, spaghetti bollock-knees, shepherd’s pie or chilli con carne offerings in the 1970s, 1980s.

On my last trip to Italy I discovered a traditional pasta dish made by stewing the patellas and testicles of a pig.
I don’t know why Spaghetti Bollock-Knees isn’t more well known.
