Several times you say to "...put an air fryer liner under the drawer...". I'm confused about this advice. What type of liner? Paper? Silicone? I'm looking at your whole chicken technique where it says "Put an air fryer liner under the drawer to catch those delicious juices.", but this advice appears for "Sausages" and "Bacon" and others. Where exactly does it go? I have an air fryer with a pull out drawer/basket. The basket has a solid bottom and a slotted tray is placed inside the basket. Does the liner go in the basket and under the tray? Surely not under the basket itself.
