A toaster has heating elements (H1, H2) arranged at opposite sides of a product (5) to be toasted. The size of the product to be toasted (5) is detected by means of a sensor, for example a mechanical sensor (2.1, 2.2, 2.3) or an optical sensor device with a photo-emitter and a photo-receiver. The power delivered by the heating elements (H1, H2) is controlled in dependence on the detected size. Thus, the power consumption of the toaster is adapted to the size of the product to be toasted and overheating of the product is avoided and a constant toasting time is obtained. |
