Use in your favorite dish!I love a good sauce. Alfredo sauce combines some of my absolute favorite things: butter, heavy cream, and cheese. It's one of the most decadent sauces you can eat, so I try not to indulge too often.... but when I do, it's magical. So, it's kind of funny that making Alfredo sauce is so simple and hardly takes any time at all.
