Not quite as we intended as what were sold as being San Marzano have turned out not to be 100% SM but Cuore di Bue and another unidentifiable type. One of our neighbors had the same problem and went back to the nursery to complain!
Anyway there is passata to be made. Very simple no onion no garlic just olive oil, chopped tomatoes and salt. Bring them to the boil and then simmer away for an hour or until you have a thick tomato sauce. The bottle in sterilised bottles.
