According to the query on Gourmet World: Fried wontons can be placed in a thermos bucket for lunch.
Although the temperature in the thermal insulation barrel will gradually decrease, as long as the insulation effect of the thermal insulation barrel is good enough, the temperature and taste of the wontons can be maintained without affecting their quality and taste.
Before placing in the thermos bucket, the wontons need to be fried and allowed to cool to avoid heat retention and condensation, which will cause the wontons to become sticky and affect the taste.
At the same time, the thermal insulation barrel needs to be cleaned and dried to prevent the wontons from deteriorating or bacterial growth due to moisture.
