Olive Garden Alfredo Sauce

Its not quite as good as the Olive Garden, but this is the best recipe for Alfredo sauce that I have been able to find. In my small town grocery store, I can't always find Romano cheese. If that is the case, I just double the Parmesan cheese. The only time I have found Romano is in the spaghetti section where they keep the Parmesan cheese that can be sprinkled over spaghetti. I bought all 5 containers and I'm glad I did because they haven't had any since.

Olive Garden Alfredo Sauce
1-1/2 cups milk
1-1/2 cups heavy cream
1/2 cup Parmesan cheese, grated
1/2 cup Romano cheese, grated
6 egg yolks
salt and pepper to taste
--------
Heat milk and cream in a heavy bottom saucepan until it begins to simmer. Turn off heat. Slowly whip in cheese, then remove from heat.

Place egg yolks in a separate bowl and slowly whip in a portion of the hot milk and cream mixture. Slowly add egg yolk mixture back into remaining cream mixture. Place back on very low heat and continually stir until simmering. Take sauce off heat so it thickens.

Season to taste with salt and black pepper. Serve over your favorite pasta.
