A method includes inserting a food item into an inner volume of a thermal container. A liquid circulating through a liquid jacket at least partially surrounding and fluidically isolated from the inner volume of the thermal container is cooled such that thermal energy from the food item is transferred to the cooled liquid. After the cooling, thermal energy from a first heating element is transferred to the liquid circulating through the liquid jacket such that thermal energy from the heated liquid is transferred to the food item. Thermal energy from a second heating element is transferred to the food item in response to a criterion being satisfied. The second heating element is different from the first heating element and is disposed in the inner volume of the thermal container.

A method of using a storage and cooking device having multiple thermal containers includes disposing a first food item in a first thermal container, a second food item in a second thermal container, and a third food item in a third thermal container. A volume of fluid is cooled and circulated through at least a portion of the device such that thermal energy from at least one of the first, second, or third food item is transferred to the cooled fluid. The device is transitioned from a first operating mode to a second operating mode in response to a criterion being satisfied. When in the second configuration, the volume of fluid is heated and circulated through at least a portion of the device such that thermal energy is transferred from the volume of fluid to at least one of the first, second, or third food item.

A heating device for a food item in a food container includes the food container that contains the food items, a cooking container that contains the food container, and a steam generation device that supplies steam into the cooking container. The food container has an opening hole that communicates with an internal space and an external space, and at least one of a food surrounding space provided between an inner wall of the food container and the food items, and between the food items. The food surrounding space and the external space are communicated with each other through the opening hole, and steam is supplied into the cooking container to heat the food items by the steam. Thereby, the heating device for a food item in a food container that can subject the food item in the cooking container to steam heating can be provided.
