They taste pretty much the same as any other fries, but the texture is really great. Crispy outside, fluffy inside.
And it works a lot better with a thick cut (1.2+ cm), the contrast between a super glassy, not oily outside and fluffy, airy inside all throughout is really good.
For the same reason I would say, don't bother with thin cut with his air fryer version. Go thick or don't bother.
