Abstract
For making a cooked waffle from batter, a waffle maker comprises a pair of opposing heater grids configured to be closed together when batter is placed therebetween for cooking, and a controllable power supply with an output coupled to the grids for supplying power thereto to heat the grids. The power supply has a cooking mode wherein a high level output is supplied to the grids during a cooking cycle and a standby mode wherein a lower level output is supplied to the grids upon completion of the cooking cycle for preventing overheating of the grids. The temperature of the grids is controlled to provide optimum cooking and to prevent overheated grids between cooking cycles.
