What occurs if the water jacket of a kettle is overfilled?

When the water jacket of a kettle is overfilled, the space needed for steam is reduced. Kettles operate by creating steam in the water jacket, which is essential for even cooking and efficient heat transfer. If the water jacket is overfilled, there is less room for steam to accumulate, which can lead to inefficient operation. The reduced steam space can hinder the kettle's ability to reach the appropriate cooking temperatures and can disrupt the cooking process.

This issue can cause problems in maintaining proper pressure and temperature inside the kettle, potentially leading to uneven cooking or longer cooking times. Therefore, managing the water level within the specified limits is crucial for the optimal performance of the kettle.
