Double-coated crispy fries engineered to stay crunchy for hours in a packed school lunch.
Rice flour gives a glassier, longer-lasting crunch than cornstarch if you have it on hand. Sweet potato fries work with this method too, but coat them slightly heavier since they hold more moisture. If packing the night before, slightly undercook the final fry and give them a 15-second reheat in the air fryer or toaster oven before boxing them up in the morning.
