A bowl is provided for rapid and repeatable high quality cooking of rice or other grains within a microwave. The bowl includes a reservoir with a floor and walls extending up from the floor to a rim. Handles are preferably provided extending laterally from the rim. A rice line is provided which is visible to a user and defines a height at which rice should be added for cooking within the bowl. A water line is provided above the rice line which defines an elevation to which water should be added for cooking of the rice. In one embodiment walls of the reservoir are tapered to accommodate boiling and frothing without boiling over and still maintaining a compact cooking space within the bowl.
