Question about Mio Star 3.5 l

MioStar's 3.5 l hot air fryer can use aluminium trays to make gratins, as can other airfryers. Aluminium trays are generally compatible with this type of appliance, as they can withstand cooking at high temperatures and allow good circulation of hot air. However, make sure that the size of the trays is adapted to the 3.5 litre volume of the fryer to ensure even cooking.
