Many people say that soaking potatoes in water makes them crispier. The idea is that soaking draws out the starch before cooking. I tried making these air fryer wedges both ways and couldn’t tell the difference. In fact, soaking the wedges in water before cooking can prevent them from crisping up if you don’t dry them enough. If you’re having trouble getting your potatoes crispy, I recommend you save time and skip the soaking process.
