Getting it right

Ninja recommends 3 minutes of preheating. (Ninja's AF100UK chart)
For even browning, spread food in an even layer with no overlapping. (Ninja's AF100UK chart)
Shake the food at least twice during cooking. (Ninja's AF200UK chart)
Cook a smaller amount for less time and a larger amount for longer, and check often. (Ninja's AF100UK chart)
Start checking 2 minutes before the time is up, and make sure food has reached a safe temperature. (Ninja's AF200UK chart)
