If it comes to the iron pot we use in the kitchen, maintenance is definitely a knowledge worth our good study. After wearing out several non-stick pots, I finally made up my mind to buy a cast iron pot. Although I was not used to it at first, after a period of adaptation and maintenance, I am now very fond of it.
For the vast majority of families, or such a simple big iron pot to use the most practical.
Today, this article focuses on the detailed knowledge of cast iron pot, including the principle and method of boiling pot and keeping pot, purchase, safety and so on.
No.1 Understanding iron pot: How to buy a pot?
According to the material, iron pot is roughly divided into 3 categories, raw iron pot with carbon content of more than 2% (cast iron pot), cooked iron pot with carbon content of less than 0.02% after purification (pure iron pot), and alloy pot with a certain proportion of other elements (stainless steel pot).
Но, во однос на површинската обработка, постојат многу различни категории. Емајлирани, со смола или боја прскани, електрогалванизирани, поцрнети со оксидација.
The characteristics of the iron pot are mainly determined by the material. Pig iron is brittle and hardly malleable, which is why cast-iron pots are heavy. Wrought iron is soft and malleable, so it can be forged into very thin pot.
Surface treatment to a certain extent can improve the iron pot is not resistant to acid and alkali, easy to rust and other shortcomings, so that it is easier to maintain, at the same time, the price can be higher.
Functionally, a bare iron pot is enough. Very durable, conservative estimate 10 years or 80 years will be fine. The price is also cheap. But some nameless iron pots may have the problem of excessive heavy metals, so it is safer to buy branded ones.
Друг фактор што треба да се земе предвид е обликот, изработката, квалитетот, тежината и другите неригидни услови, според нивните преференции на линијата.
No.2 Why should the iron pot be maintained
When the iron pot was first bought, it was silvery white of pure iron itself. At this time, it is not only fried what sticks to what, but also easy to rust. You can’t cook like that. We have to figure something out.
Најдиректниот начин е да се премачка со слој што не лепи. Употребата на PTFE и други материјали како слој што не лепи, тоа е само од пред неколку децении. Методот што го користиме уште од античко време е всушност позлатување со масло.
It was discovered early on that cooking with oil in an iron pot would get better and better, and the pot would get darker and less sticky. In order to achieve this initial effect in the first place, there is the “boiling pot” procedure. The traditional way to boil a pot is to clean it and cook it over and over again with lard.
Grease in high temperature, aerobic conditions will occur decomposition, oxidation, polymerization and other reactions, and the so-called pot and pot, in fact, is the use of these reactions.
Во процесот на реакција на маснотиите на висока температура, некои мали испарливи молекули се претвораат во саѓи и си заминуваат, а некои други молекули формираат големи молекули преку полимеризација, дехидрација и кондензација и други реакции за да се прикачат на железниот сад, што е потеклото на слојот од црн оксиден филм на железниот сад. А железото е одличен катализатор за овој процес.
So it’s exactly the same principle as a nonstick pot. Equivalent to our own use of the nature of grease to iron pot “plated” a layer of high score non-stick layer, but the composition is complex, almost every pot has its own unique composition, can be made into a non-stick pot.other materials made of non-stick pot, coating scratch the pot can not be used. But our homemade rust-proof coating, when scratched, can be maintained, and it’s a good pot again. This is the reason and principle of iron pot maintenance.
No.3 Iron pot maintenance methods
Нашата цел е едноставно да добиеме појак, подебел оксиден филм.
The tighter the bonds between the molecules, the stronger they are. So the more unsaturated the oil, the better. Flaxseed oil is the most prone to oxidation polymerization and the most effective oil. Soybean oil, sesame oil, sunflower oil, corn oil and other polyunsaturated fatty acid content is also good.
Може да се користат и други масла, но мрежата на врски не е толку густа како, да речеме, маслото од ленено семе. Свинската маст, која често ја користиме за варење во тенџерето, е само традиција што се пренесувала од генерација на генерација и не е толку добра како обичното растително масло во однос на практичните резултати.
With the ingredients in place, the next thing is to get them ready to react. The correct way to do this is to evenly and thinly grease the inside of a pot with kitchen paper, then set the heat on high and turn the sides of the pot until it is all dry and there is not much smoke. Then apply a thin coat of oil, burn again, repeat several times. (i.e. boiling step)
The uniform overlapping of several layers of oil film makes it physically denser. General online sellers will provide free boiling service. If you do it yourself, be aware that the surface of the new factory pot will be covered with mechanical protective oil and must be carefully washed off. You can boil a pot of water and put it on fire to dry, then wash it with dish washing liquid and put it on fire to dry, repeat 2-3 times.
If an iron pot is badly rusted during use, remove the rust with vinegar and a brush before returning to the pot.
При користење на пеглата, маслениот филм природно ќе станува сè подебел и подебел. Гребнатините предизвикани од локално гребење може да се поправат со само еден или два дополнителни садови. Во ред е повремено да се користи за варење вода.
The process of “pot cultivation” is not complicated, we also break it down into two basic goals: to prevent rust and reduce oil film shedding.
Спречување на 'рѓа: Клучната точка на спречување на 'рѓа е водоотпорноста. Обавезно исушете го или исушете го по секоја употреба и не држете вода преку ноќ. Ако нема да го користите долго време, исушете го во слој масло и чувајте го на ладно и суво место.
Reduce oil film shedding: We often say that the iron pot should not be washed with dish washing liquid, can not be used to boil water, at first use less acidic seasoning, these are reasonable.
Then a great final sentence. Ladies and gentlemen, by this point, you should already know how to boil and keep a pot. This is enough, next please rest assured to operate boldly. Don’t stick to the steps I’ve outlined above, and don’t worry about what you’ll do if you don’t get it right. Iron pots are very durable!
