Abstract A high frequency heating oven has an oven-defining housing having a heating chamber defined therein and a hingedly supported door for selectively closing and opening an access opening leading into the heating chamber. A cooking vessel, such as a saucepan or saucepot, is provided including a weighting plate removably accommodated within the vessel. The weighting plate is used to restrain the food being cooked in position within the vessel during the heating of the food by the use of the high frequency heating oven. The plate is made of dielectric material and has a plurality of vapor escapement holes.
