Do I need to fry the iron pan in oil after it is used up?

1, 2, there are two steps to boiling the pot: the first step is to burn the pot to green (if the factory is coated with anti-rust oil.

In this step, the anti-rust oil should be burned and volatilized to produce a lot of smoke, and it is necessary to do a good job of ventilation), and then use dish soap.

Wash clean, a layer of oxide layer is formed on the surface of this step, which is not easy to rust; The second step is to use more lard.

Or vegetable oil to coat the whole pot, heat, and then put in the unwanted vegetable leaves and stir-fry until they become soft and black, and throw them away, this step can form a layer of oil film on the surface of the pot, which can prevent rust and prevent sticking to a certain extent. After that, wash with water and brush the pot with a bamboo brush. 3. In addition to the rare use of special technology to process iron into high-end products that can be used without boiling, the traditional raw and cooked iron pots need to be boiled.

4,5 Cooking pot: Before stir-frying, pour a large amount of oil into the pot and heat it, turn the iron pan to let the hot oil stain the inner wall of the iron pot, pour out the oil after the heat of the whole pot reaches more than 200 degrees, add cold oil and stir-fry. The oil from the pan can be reused several times, or it can be used for stir-frying after it has cooled.

Raising pot: The oil film is not sticky, but the oil film is not firm. The film of vegetable oil will become thicker when you fry often, which is why the iron pot is easier to use the more you use it.

However, dish soap will seriously damage the oil film, so iron pots should be washed with water and bamboo brushes to avoid damaging the oil film. In addition, frequent stewing will also take away the oil film, so try to stir-fry the wok as much as possible. Anti-rust:

After washing the pot, you should use the fire to dry the water, and if you don't need to deliberately apply a layer of oil on the surface of the pot for a long time to prevent rust. Fix: In case it rusts, or the paste pot can't be cleaned up, you can consider reopening the pot.

First, use vinegar to burn the pot to corrode off the attachments; Then rub the pot clean with a steel wool ball and wash it with dish soap. At this time, the oil film and oxide layer inside are destroyed, so repeat the process of boiling the pot. Except that there is no anti-rust oil to volatilize, the other processes are basically the same as the first boiling.

Yes, you need to fry it in oil after the iron pot is used up. This step is called "scorching pot", that is, before stir-frying, pour a large amount of oil into the pot to heat, turn the iron pot to let the hot oil stain the inner wall of the iron pot, and pour out the oil after the heat of the whole pot reaches more than 200 degrees, and add cold oil to stir-fry. This step can be reused several times, or it can be used for stir-frying after it has cooled.

The iron pot that I just bought back has to be fried with lard before it can be used, in fact, this is called boiling the pot. Newly bought iron pots generally need to be boiled before they can be used conveniently. For a rough new pot, it's easy to fill the pan body with oil, which prevents rust.

After the pot is covered with oil, you can turn the fire slightly larger, so that the pot body is heated in the oil, it will be a little black, but it doesn't matter, after the high temperature and the iron pot burned with oil, it will not be easy to paste in the future.

Woks are generally iron pots, which can be divided into pig iron.

with wrought iron. <>

Wrought iron is light and thin, and it is easy to scorch the pot when the fire is large;

Pig iron is bulky but thick, evenly heated, easy to control, and replenishes iron.

See if the surface is smooth, but can not be required to be smooth as a mirror, due to the casting process.

As a result, the iron pot has irregular shallow lines. The defective and small protruding parts are generally iron, which has little impact on the quality of the pot, but the small pits are more harmful to the quality of the pot, so you need to pay attention to it when purchasing. Second, "listen", the uneven thickness of the pot is not good, when buying, you can turn the bottom of the pot to the sky, use your fingers against the center of the concave surface of the pot, and knock it with a hard object.

The louder the pot sound, the greater the vibration, the better. In addition, the pot with rust spots does not necessarily mean that the quality is not good, the pot with rust spots indicates that the storage time is long, and the longer the pot is stored, the better, so that the internal organization of the pot can be more stable, and it is not easy to crack when it is first used.

Ordinary iron pots are easy to rust if the human body absorbs too much oxygen acres of refluxed iron.

That is, rust, will cause harm to the liver, so it is not advisable to hold food overnight. At the same time, try not to cook soup in an iron pot, so as not to disappear the cooking oil layer on the surface of the iron pot that protects it from rust. Detergent should also be used as little as possible when brushing the pot to prevent the protective layer from being brushed out.

After brushing the pot, try to wipe the water in the pot to prevent rust. If there is a slight rust, you can use vinegar to clean it. When stir-frying in an iron pot, stir-fry quickly and add less water to reduce the loss of vitamins.

It is not advisable to cook bayberry in an iron pot.

Hawthorn, begonia and other acidic fruits. Because these acidic fruits contain fruit acids.

When it encounters iron, it causes a chemical reaction.

Low-iron compounds are produced, which can cause poisoning when eaten. Cook mung beans in an iron pot because of the tannins contained in the bean skin.

After encountering iron, a chemical reaction will occur to form black iron tannins, and the soup of mung beans will turn black, affecting the taste and digestion and absorption of the human body.

No need to wash! Burn the pot directly and smear it with lard, repeat two or three times! Then cool down naturally!

Recommendation: buy a piece of lard fat in the vegetable field first, and then wash the iron pot and heat it with fire, the hotter the better (especially the pig iron pot) After the pot is red, use the lard fat prepared in advance to wipe the red iron pot vigorously, wipe the whole pot once to 2 times and then continue to heat, wipe it twice, and then wait for the pot to cool down naturally, if the new pot is not handled well, it is easy to rust.

Personal thoughts: The heated iron pot has a large molecular gap, and the lard penetrates into the iron molecular gap after wiping it with lard, so that a protective film is formed between the molecular gaps, so it is not easy to rust.

Iron pan is a traditional kitchen utensil for cooking food, which generally does not contain toxic substances, but often oxidizes when exposed to water. The main varieties of iron pots are printing pots, ear pots, flat belt pots, oil pots, pancake pots, etc. The main component is iron, but it also contains small amounts of sulfur, phosphorus, manganese, silicon, carbon, etc.

Iron pots are divided into cast iron pots and wrought iron pots: pig iron pots are made of gray iron melting and casting; Wrought iron pot is made of black iron forging or hand hammering, which has the performance of thin pot blank and fast heat transfer. At present, there are some theories that iron pots can supplement iron, but there are no experiments to prove that cooking in iron pots can replenish iron.

Because ordinary iron pots are prone to rust, the human body absorbs too much iron oxide, that is, rust, which will cause harm to the liver. Therefore, when people use the iron pot, they cannot flush the iron pot with water, and they need to abide by some principles of use in order to be healthy.

After frying a dish, brush the pan once and stir-fry another dish. After each meal, the inner wall of the pot must be washed and wiped dry to prevent the pot from rusting and producing iron oxide that is not good for human health. Some people are accustomed to putting the boiled iron pot under the faucet to rinse, when the water is twisted, the smoke rises instantly, and the fine suspended particles lurking in the air increase sharply, which is not conducive to health and should be avoided.

Do not use an iron pot to serve food overnight, as iron will dissolve iron under acidic conditions and destroy vitamin C in the dish. Try to use as little detergent as possible when brushing the pot. If there is a slight rust on the inside of the pot, it can be cleaned with vinegar.

For iron pots that are seriously rusty, black slag, and black skin, they should not be used again. The iron pot should not be used to boil medicine, and it is not suitable for slag filial piety to cook mung beans in an iron pot. Try not to use an iron pot to cook the soup, so as not to disappear the cooking oil layer on the surface of the iron pot to protect it from rust.

Every time you use an iron pot to cook a dish, remember to wipe it dry and dry, otherwise it is easy to rust, and always use a rusty iron pot to fry vegetables, which still has an impact on your health.

The oil has been put in the iron pot for more than a month and then the oil has deteriorated, after brushing the pot, boiling the pot with boiling water, can the pot still work.

If the oil in your pan has spoiled, it is recommended not to use the oil to cook or fry the ingredients, because the spoiled oil will not only destroy the nutritional value of the food, but may also affect human health. For iron pots, it is recommended that you pour out the spoiled oil from the pot and then wash it with salt and water. You can use some lemon juice or white vinegar as a cleaner to remove grease from the surface of the pan.

You can then wash it again with salt and water, dry it with a kitchen paper towel, and then coat the pan with a thin layer of cooking oil to avoid rust. Finally, bring boiling water to a boil, which will completely kill the bacteria. This way, your iron pot can be used again.
