Need a sauce for a delicate lobster ravioli? Here's your sauce! This sauce can also be used for mushroom or butternut ravioli's with equal success. This sauce is definitely not for dieters, but shines at a formal Italian dinner where calorie counting is not heeded. Make sure you use a good parmasen cheese (not something out of a box). A nice Sauvignon Blanc is a great accompaniment to this sauce.
