    The addition of the egg yolk intrigued me, so I gave this sauce a try. It is so good! I served mine up with some chicken. I only had Parmesan, so I didn't add any Romano. I also added a tough of garlic after reading some of the reviews.

    Very similar to my recipe except I didn't have an egg yolk in mine. I add garlic, chicken breast, mushrooms and roasted asparagus to mine. Do make sure to add the nutmeg - it may sound odd but it gives the dish more depth.

    I've made Alfredo for years. But this recipe was exceptionally good. At first I was a bit snobby and thought I would never use a recipe other than my own creation. USE THIS!! The egg yolk made all the difference. I hesitated to put nutmeg in though. Maybe next time. I had no problem with the butter separating. It was full, thick, creamy and no waste. The amounts were spot on. I used homemade fettuccini (a bit more than 4oz.) and we tossed it with the rest of the sauce and had it for lunch!

    I loved this sauce! The first time I made it, I added some sweet peas to it and that brought out the flavor even more. Next time I may add in some bacon or prosciutto!

    Update: Made this again tonight and again it was delicious. This time I added chicken along with the sweet peas. I only had spaghetti so I used that instead. I would say this is a forgiving recipe too since I accidentally let it start to boil but the sauce still came out fine.

    My family loved this! I didn't have any Romano, so it was all Parm. I added chicken breast and fresh broccoli. This will become a staple dish.

    I loved this recipe. It's easy and quick to make. But the butter in always separates from the sauce. it's still tasted really good, but there is a puddle of butter on the bottom of my plate. What can I do from that not happening next time?
