1 1/2 T flour
1/8 t minced garlic (or more to taste)
2 c heavy cream
1 c Parmesan (I've used fresh, but feel like it comes out better with the powdered craft kind)
Sprinkle of dried or fresh chopped parsley
Melt butter. Add flour and garlic and cook one minute. Add other ingredients. Don't boil, but continue to cook until softened.
Serve over cooked fettuccine noodles. Also delicious over the top of spaghetti with marinara sauce!
