This isn't Ragu or Prego, so don't pour it on too thickly. In this case, less is better. Note: the sauce is especially tasty if it can be made several hours ahead. The flavors develop better. Also, the bacon really is essential to this dish. It adds an interesting taste dimension that the olive oil doesn't have. It adds a smoky dimension to it; it is really indescribable. It is very tasty without the hot peppers also. We usually add the peppers at the table rather than in the cooking. 4 cups penne pasta (mastaciolli or other dry pasta would be fine).
