Should I add oil or heat the pan first when frying eggs

It is more appropriate to heat the pan before adding oil to stir fry eggs, which can prevent harmful substances from being produced due to high oil temperature and reduce the probability of sticking to the pan. The specific operation method is related to factors such as oil selection and fire control.

When stir frying eggs, first heat the empty pan to a slightly smoky state, then pour in cooking oil to quickly moisten the pan, and wait for the oil temperature to rise to 50% or 60% hot before laying the egg mixture. This operation utilizes the principle of thermal expansion and contraction to shrink the micropores of the pot body, forming a physical non stick layer, while avoiding the production of harmful substances such as acrylamide from cold oil at high temperatures for a long time. When using an iron pot, it is especially important to preheat it thoroughly. If the pot is not sticky, the preheating time can be shortened appropriately. Peanuts, rapeseed oil, and other high smoke oils are more suitable for high-temperature quick frying, while olive oil is recommended to be cooked in a hot pot with cold oil.

Some families prefer to stir fry eggs in a cold pot with cold oil directly, which can avoid the risk of oil splashing and scalding. However, in a low-temperature environment, the egg liquid is prone to penetrate the micropores of the pot and cause sticking to the bottom. When using an induction cooker, this situation is more likely to occur due to slow heating. If using this method, it is recommended to choose a non stick pan and keep the heat low throughout the process. Do not flip the egg mixture before it solidifies. Regardless of the method, adding a small amount of water or cooking wine when beating eggs can enhance the tender and smooth taste, and sprinkling salt before serving can prevent premature denaturation and dehydration of proteins.

In daily cooking, different methods can be alternately used to observe which one is more suitable for the characteristics of one's own stove. Pay attention to controlling the oil temperature to not exceed 180 degrees to avoid repeated heating of the grease. Stir fry with vegetables rich in vitamin C, such as tomatoes and green peppers, to improve iron absorption. People with gallbladder disease should reduce their oil consumption, and children and the elderly are recommended to use low-temperature cooking methods such as steaming eggs or stir frying eggs in water.
