I know it's unhealthy, but in my opinion, it doesn't get much better than fresh, hot McDonald's fries. (and a small fry is only $1, just to let you know)
Well, Kenji Lopez-Alt has created the perfect french fry that can be made at home! (or so he claims.) Granted, it looks like it'd take a little work, but sometime I'm going to give these a try!
He also has written an article about the science behind the recipe, which I found to be an interesting read.
