Easy to prepare and very tasty! Made it with light sour cream. Added garlic powder, pepper and a dash of salt. Used over noodles, broccoli and chicken. Will be adding this to the recipe collection for a quick meal that the whole family will love :)

This recipe is excellent. Before you add the sour cream and egg yolk, saute some minced garlic in the melted butter. It makes a great flavor addition.

Wow! Easy and tasty. My husband is a very picky eater, typically does not prefer sour cream, but loved this sauce. Used it in a pasta toss with whole wheat penne, sweet Italian sausage and green peas. Recipe was added to the family recipe box before dinner was over!

College student approved. This is sooo tasty and affordable, also very impressing to the friends.

Found this recipe many decades, ago on Ronzoni fettuccine box. It is to die for. Lost the recipe over 20 years ago, but will be making it again, soon. It is a keeper and one to pass down. Making a copy of it and will never lose it again. Thank you, you made my life happier.
