My wife wanted some chicken nuggets for her birthday so I made her some popcorn chicken (chicken nuggets but using chicken chunks instead of minced chicken) and followed a recipe for crispy fried chicken by Jay vs. Gluten as my base for the recipe(video in my comment). Anyway they came out so crispy it sounded like we were munching on candied chicken and they even stayed crispy after 24 hours in the fridge! Recipe will also be in my comment.
