Wow. Saw this last night on his new TV programme and had to try it. So simple and so tasty! I had to make a couple of substitutions because we can't get everything here in Andorra. Getting a large piece of pancetta would have been challenging, so I replaced with smoked bacon lardons which are freely available. Also, pecorino? The Andorran lady looked at me as if I was mad, and what's wrong with a nice bit of Catalan manchego? I'm sorry, but I replaced it with parmeggiano! Remember you should always add your pasta to the sauce, not the other way around, so make sure you use a big deep frying pan.
