One of my top five favorite recipes of all time would have to be this version of alfredo sauce. I got it from an old boyfriend's sister, probably the best thing to come out of that relationship... just kidding, mostly.
While I was at the gym Monday night, I was thinking about food (naturally) & realized I had all the ingredients for it. I jumped off the elliptical immediately.
This recipe is a definite indulgence because it is just straight up not good for you. Which is why it's a favorite.
