Five Guys cajun fries taste great, but the texture is the worst in the business. I have no idea why they use peanut oil - the whole point of frying in peanut oil is that you can get it extra hot without it smoking, so you can get things nice and crispy. But their fries are the exact opposite of crispy!
Last time I had Wendy's fries, they were about the weirdest fries I've ever eaten. It was like they were a crispy shell and hollow on the inside.
And I've never had crinkle-cut fries that weren't a disappointment to potatoes. It seems like the extra surface area should be good for texture, but damn every time, the taste is as bland as can be.
