The tip I hear the most with fries is, to double-fry them. First fry them till they are cooked, but still pale on the outside. Then let them cool off. Then fry them again, till they are crispy.

This should improve overall crispiness, but also potentially keep sem good for longer, as you´ll reduce water content.


That said, fries are greatest when they are hot. So try to make smaller portions and then make some more if you need them. With the above tip it´s easy, as you can have them prepared and the second fry does not take long.
