Spaghetti Bolognese is one of my absolute childhood memories of sitting at my grandmother’s table - she called it “pasta asciutta”: I don’t know why she used this term, and I remember that as a child it took me quite a long time to understand that it was the same dish that was called “spaghetti bolognese” everywhere else. There are about 700 variations on the recipe - here is one that is pretty close to my grandmother’s: I don’t remember any celery or red wine in the sauce, and she hardly ever used spices like thyme, oregano or basil.
