Abstract
Abstract This invention provides a food material-container combination which allows the food material to be cooked and solidified by simple operations without a pot, and which simplifies the work of cleaning up after cooking. Referring to FIG. 1, a self-standing container 11 has an opening 12 at the top portion thereof. A food material such as tofu material is charged in the container 11 together with water. The upper portion 13 is sealed by folding it by hand. The container and contents are then thoroughly shaken, whereafter the content of the container 11 is heated by a microwave oven. After a prescribed period of heating, the container 11 is taken out from the microwave oven and the container is cut along the line 16. The end product can then be removed.
