Understanding Traditional Alfredo Sauce

It’s a simple recipe, with butter and parmesan perfectly blended to create a velvety sauce enveloping the fettuccine. But what is so special about it?  Why not just dump butter on noodles? The quality and freshness of the ingredients, of course, but above all the method of emulsification used by Alfredo di Lelio, inventor of the fettuccine that bears his name, born in Rome in 1883. He is credited with putting this creamy dreamy sauce on the menu at his family restaurant in Piazza Rosa.  Today, it turns up in over 800 American cookbooks published from 1933 to the present. 

So, let’s talk about emulsification, the method used to emulsify (or blend together) butter, cheese and cream without it separating to make the best ever authentic Italian alfredo sauce that would make Alfredo proud.

Our secret weapon is an egg yolk, which helps to bind the fat (butter) and liquid (cream) components of the sauce together, creating a smooth and creamy texture.  Essentially, it helps stabilize the sauce by preventing the fat from separating out.  

What you'll need

While Alfredo’s recipe most likely consisted of only 3 ingredients, this version is a blank canvas allowing you to throw in some fresh tarragon, dried herbs, or even a pinch of saffron, to transform your simple dishes into elegance.

• Heavy cream – the point of making an authentic Italian alfredo sauce means using heavy cream.  Yes, of course you can use half and half or milk, but you will compromise the overall creaminess, flavor and texture. 
• Egg yolk – the secret ingredient to keeping our sauce from separating and achieving a creamy smooth texture.
• Butter
• Garlic clove
• Parmesan –  Please, please, please use freshly grated Parmesan because it has a richer, more intense flavor compared to pre-grated versions. When grated, the cheese is at its peak freshness, which means it delivers a nuttier, sharper taste that enhances the overall dish.  And when grated the cheese is fluffier and melts more smoothly into the sauce. Pre-grated Parmesan often has anti-caking agents that can prevent it from melting evenly, leading to a grainy texture in your sauce.  I hope this convinces you to grate your own!
• Black Pepper

How to make authentic Italian alfredo sauce recipe

To make this small-batch authentic Italian alfredo sauce recipe, we are going to do some blending of ingredients in stages.   First, in a medium bowl or large measuring cup, whisk the cream and egg yolk together until combined. 

Now we will turn to the stovetop, and in a medium saucepan, melt the butter over medium-high. Adding the garlic to flavor the butter by sautéing until fragrant and sizzling.  Slowly, pour the cream-yolk mixture into the garlic butter, stirring the entire time, immediately reduce the heat to medium.  Cook this mixture until it is hot to the touch but not boiling.  This will take about 5 minutes.

Now it’s time for the freshly grated Parmesan.  Whisk it  in little by little, and cook over medium, whisking frequently.  We want the cheese to melt smoothly.  Continue to cook until creamy and thickened, 3 to 5 minutes. Season to taste with pepper.  That’s it. So easy and so rich, creamy and delicious!
