I've been making this recipe for years, but never posted it because I prefer to use Cassava flour (tapioca starch), but it was only available at specialty grocery stores until fairly recently. If you prefer, you can use corn starch, but I'm unaware if there would be a change in measurements.

If you're in a pinch, this homemade Alfredo sauce is a wonderful way to elevate a box of pasta. Evaporated milk adds a slightly nutty and sweeter flavor than a store-bought jar of Alfredo sauce. There's a hint of garlic flavor, too. If you don't have cassava flour, corn starch works well as a thickener. We added the Alfredo sauce to pan-seared chicken served over pasta as Chandra suggested, and everyone enjoyed it.

    Gradually whisk in the slurry into the warm milk mixture.

    Continue to cook, stirring constantly, for about 3 - 5 minutes until the sauce begins to thicken slightly.
