The safe approach

Loose paper, non-heat-safe plastic and overly wet batter can create avoidable risks.

  • Keep airflow paths and the heating element clear.
  • Use only heat-safe materials that fit securely in the basket.
  • Check the instructions for your exact appliance model.

When to stop

Stop cooking if you notice melting, sparks, flames, electrical odors or repeated heavy smoke. Unplug the appliance and contact the manufacturer when the cause is unclear.

Frequently asked questions

Preheating helps browning for short cooks, but the instructions for your model take priority.

Check at the early end of the range and change time in small increments.
