Abstract: Systems, methods, and media for induction heating a first food vessel of a first size and a second food vessel of a second size include a base defining a well to separately receive the first food vessel and the second food vessel. A plurality of coil assemblies are mounted to a bottom side of a tray. The plurality of induction coils are electrically coupled with an inverter of the induction heating system. A sensing system is configured to indirectly measure a temperature of the first food vessel when the first food vessel is resting in the well and the second food vessel when the second food vessel is resting in the well. A controller is communicatively coupled with the sensing system and the inverter and is configured receive the temperature measurement from the sensing system, and control the inverter according to the measurement.
