Abstract
A device for covering food (306) during microwave heating includes a microwavable flexible sheet (100) having a substantially smooth, food-facing surface (102) that is free of openings. The sheet (100) has a configuration including size, shape, and weight distribution for flexibly draping the sheet (100) over the food (306) on a rigid structure (304) such that the flexibly draped sheet (100) overhangs and folds loosely over an outer perimeter of the rigid structure thereby forming at least a partial enclosure around the food (306) when the sheet contacts at least a portion of an outer perimeter of the food-containing rigid structure (304). During microwave heating, the at least a partial enclosure around the food (306) substantially contains food-splattering (308) inside while allowing steam (312) to escape through an opening (310) formed between the flexibly draped sheet (100) and the outer perimeter of the rigid structure (304).
