1. An induction warmer station, comprising:
a housing;
a cooktop coupled to the housing;
an induction coil positioned in the housing adjacent the cooktop; and
a controller configured to maintain a target power-to-surface-area ratio by adjusting the frequency of a current input to the induction coil based on an indication of a response of an output current from the induction coil to a change in surface area of load material placed on the cooktop.
