Fettuccine Alfredo Sauce

From: Shelly...
4 T butter
1 cup whipping cream
4 egg yolks
1/3 cup freshly grated Parmesan cheese
1/4 lb. smoked salmon (this is optional and can be used instead of chicken)
salt and pepper to taste
In a medium sauce pan melt butter and add your cream, simmer uncovered stirring over low heat for about 15 minutes (until it has reduced some).  Add a couple of tablespoons of cream to your egg yolks and whisk vigorously, then add this to your hot cream.  Add your parmesan cheese and salt and pepper, allow to thicken (continually stirring).  At this point you could add grilled chicken (my favorite) or salmon.  Serve over hot Fettuccine noodles.
