Once I had all the ingredients it was simply a matter of throwing them in the pot. Well, peeling the onion and cutting it in half first.
My that is a lot of butter.
That's pretty well it. It simmers away for a while. The taste was pretty poor until the last few minutes, and then it seemed to come together in the end - good enough perhaps for it to be eaten out of the pot, as Marcella promises.
Of course I needed the pasta. Spaghetti I think.
And a bit of parmesan cheese.
The final product was very rich, and I must say, not as enjoyable as my other pasta dishes. I won't be making it again, at least to eat as a main course. Or even a first course. I might try again with better tomatoes, and perhaps as a sauce for gnocchi. But I must say quite disappointing I'm afraid. Pity.
