A food package for cooking of the food in a microwave oven is formed of a heat-resistant synthetic resin impermeable to oil and moisture and has at least one opening for allowing steam to escape when the internal pressure in the package is increased beyond a certain value by the steam generated during heating. The number of openings and the size of each opening are selected with consideration of the package volume or size and the type of food to be packaged so as to adjustably maintain within the package a pressure and a temperature each of which are within a range of predefined values during cooking in the oven. The package distends with increase of the internal pressure to provide a visual indication that cooking is complete. A method of cooking the packaged food comprises using the described package which adjustably maintains the internal pressure in the package within the range of about 1.00 to about 1.15 atm and the temperature within the range of about 100°to about 105°C. The steam is allowed to escape through the opening for a period of about 1 to about 10 seconds.

A food receptacle for electronic oven cooking of food, the receptacle being transparent to microwave energy and composed of a heat-resistant synthetic resin impermeable to oil and moisture and having between one to six steam-controlling openings formed in and extending through the thickness of the receptacle, from the inside to the outside, the receptacle being inflatable with increase of the internal pressure induced by the steam generated during heating of the food, up to a predetermined pressure when the steam is vented through said openings, the size of each opening having a diameter of 0.5 to 2.0 mm/300 cc. of receptacle volume, and the number and size of the opening being selected such that the internal pressure in the receptacle is adjustably maintained in a range of about 1.01 to 1.15 atm. and the temperature in the receptacle is adjustably maintained in a range of about 100°to about 105°C. by the steam generated during the electronic oven heating of the food and such that the inflation of the receptacle is observable and provides a visual indication that cooking is complete when the steam has vented through the openings for a predetermined time.
