What is a key consideration when cooking with frozen items in the fryer?

When cooking with frozen items in the fryer, oil maintenance is a key consideration. Cooking frozen foods often leads to the release of moisture as they thaw and cook, which can introduce excess water into the frying oil. This excess water can lower the oil's temperature significantly, leading to longer cooking times and potentially resulting in greasy or unevenly cooked food.

Additionally, incorporating frozen items can cause the oil to break down more rapidly due to the higher moisture levels and temperature fluctuations. Proper oil maintenance, including regular filtering and changing of oil, ensures that it remains clean and at an optimal temperature for frying. This not only helps in achieving better food quality but also prolongs the life of the oil, making it a crucial aspect of the frying process when using frozen items.
