Abstract
Abstract A package for cooking a waffle in a microwave oven is provided, comprising a microwave transparent tray about 28 to 38 mm deep, a lossy susceptor film lid having defined reflectance and absorbance, placed about 3 to about 10 mm over the waffle, providing means for moisture to escape. The waffle is coated with an edible food conditioner, to provide improved microwave susceptibility to the surfaces of the waffle. The waffle may be cooked alone or in the presence of a sausage side dish.
