What issue results from placing piping hot tamagoyaki directly into an airtight container?

Answer

Condensation leading to sogginess

When hot food, such as freshly cooked tamagoyaki, is sealed immediately into an airtight container before being placed in the refrigerator, the temperature differential causes immediate condensation to form inside the sealed environment. This trapped moisture settles onto the delicate, layered structure of the omelet. Excess moisture is detrimental to tamagoyaki, especially when aiming for a pleasant texture, as it results in sogginess, which compromises the intended delicate structure that makes the dish appealing.
