The kitchen equipment that must be used in an airtight condition is the pressure cooker. A pressure cooker is a cooking vessel that seals in steam and creates a high-pressure environment to cook food quickly. To function properly, the pressure cooker must be sealed tightly to prevent any steam from escaping. If the pressure cooker is not used in an airtight condition, the steam will escape and the food will not cook properly, which can result in undercooked or overcooked food. Additionally, the pressure cooker may not reach the necessary pressure levels to properly cook the food if it is not airtight. Therefore, it is important to use the pressure cooker in an airtight condition to ensure that the food is cooked correctly and to prevent any potential safety hazards.
