A container has a patterned susceptor region in the bottom, a fold region between the bottom and the sidewall of the container, a sidewall region, and a flange region that forms a flange or lip of the container. The patterned susceptor region includes arrangements of microwave-interactive features disposed generally along respective close plane curves, which reduces overheating and increases the filling temperature of the food product. The fold region contains microwave transparent features that minimize de-lamination of the container in the folded region, and also create a generally transmissive area in the vicinity of the heel of the food product to improve the cooking thereof. The sidewall region shields the periphery of the food product so that it is not overcooked while promoting an appropriate degree of pie dough shell browning. The flange area is transmissive to promote an appropriate degree of cooking of the food product crust.

The container is particularly useful for reheating large blocks of frozen food.

RF energy provided by electrodes positioned between a product is used to heat a product that exhibits a variable impedance during the heating process. As the product's impedance changes during the heating process, RF heating system impedance can be maintained constant by adjusting the distance between the electrodes, adjusting the impedance of a variable impedance device connected between the RF power source and an electrode, or a combination of electrode distance adjustment and impedance adjustment of the variable impedance device. The system is particularly applicable to the heating or pasteurization of bulk food products with multiple heating zones.
