Plate with practical multiple uses: as a classic serving plate for cakes, tarts, etc.; upside down for extra space with a high rim; as a universal serving plate; stackable thanks to a retractable handle; additionally with a practical universal insert that creates double the space for transporting canapés and much more, up to a height of 5 cm. A simple 90° turn of the insert is sufficient and serves as a ventilation grid for defrosting. Individually refillable battery can be used between the serving plate and the universal insert, as a cooling battery to keep grilled meat fresh or to cool fruit and cream cakes, and as a heat battery to quickly defrost frozen cakes.
