The safe approach
Perforated parchment can be suitable when food weighs it down and airflow stays open.
- 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.
