Ever had Five Guys? They do now what McDonald's used to do, except they don't peel the potatoes. They wash them and run them through the cutter right into the oil. Even their fries taste like crap when they get cold. You can't nuke 'em, either. You have to warm 'em back up using the oven. They even have the source farm's name written on a sign. Every time I've been, they've been from Idaho, usually near Pocatello or Idaho Falls (I'm from there, but currently live in New Mexico).
You have to wash them after cutting. That’s the key. I remember at least a quarter to half inch of starch buildup per load in the sink after washing.
Actually, my experience with FG fries is they are larger in size, and I have driven 20 miles with them and even nuking they were better than MDs 5 minutes away.
That is the key point most people are missing, but you understand: You cannot travel home with these fries from anywhere.
They ALL taste like crap once they drop below the threshold where they are just barely too hot to comfortably pick up with your finger.
You must eat them immediately, or they are all disgusting, be it McDonalds, Five Guys or Burger King.
