Spicy Tomato Sauce

This is a good general-purpose tomato sauce, made by the simple expedient of cooking good-quality tinned tomatoes with, in this case, garlic and chilli. Other flavourings, say oregano or basil, could easily be substituted. The addition of some sautéed diced pancetta would give you a matriciana sauce, one of the nicest of the traditional pasta sauces, and a stand-by in many Soho Italian gaffs.
