Here is the Amatriciana recipe (some aspects of this are debated within my family and you may want to adapt it too):
For 4:
-Put a generous amount of olive oil in a large saucepan and add one packet of unsmoked streaky bacon, cut into pieces about 1-2cm square. Cook the bacon until fairly well done, then remove from the oil.
-In the same oil fry a finely chopped medium onion slowly - for around 15 minutes - until very well cooked but not burnt!
-Add chilli - I would advise 1 green chilli (possibly with seeds removed, depending on how into spiciness you are)
-Add 2 tins of tomatoes and let the sauce reduce on a low-medium heat for around 45 minutes
-Towards the end (about 10 minutes before serving) add the bacon back in.
Service with lots of freshly grated parmesan, ground black pepper and (optional) chopped parsley on the top (and a glass of red wine!)
Oh, and pasta of course - pretty much any kind works, large shells or large penne (can't remember Italian names), or spaghetti is particularly good, plus a crispy salad with a sharp dressing and some avocado, cucumber and tomatoes is lovely!
