A method of using a fluid-immersion storage and cooking device having a thermal container that defines a first volume and a second volume includes disposing a first food item in the first volume. A second food item and a third food item are disposed in the second volume in a first position and a second position, respectively. A volume of fluid having a first temperature is circulated through the first volume to transfer thermal energy to the first food item. After a predetermined time, at least a portion of the volume of fluid is heated to a second temperature. A portion of the volume of fluid is conveyed to the second volume such that (1) the second food item is substantially submerged in the portion of the volume of fluid and (2) the third food item is disposed substantially outside of the portion of the volume of fluid.
