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)
