I learned to make spag bol from Cooking In A Bedsitter, Jack. I've been doing more or less the same recipe for forty years now. I found out that it's actually completely inauthentic and that true Italians would sneer at it. But my family revolted when I tried the real McCoy on them. They are well and truly conditioned. So back to Katherine Whitehorn, Gawd bless 'her!
