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).
Por për sa i përket trajtimit sipërfaqësor, ka shumë kategori të ndryshme. Të emaluara, të spërkatura me rrëshirë ose bojë, të galvanizuara me elektrolizë, të nxirë nga oksidimi.
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.
Një faktor tjetër që duhet marrë në konsideratë është forma, prodhimi, cilësia, pesha dhe kushte të tjera jo të ngurta, sipas preferencave të tyre në linjë.
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.
Mënyra më e drejtpërdrejtë është veshja me një shtresë jo-ngjitëse. Përdorimi i PTFE-së dhe materialeve të tjera si veshje jo-ngjitëse, kjo ndodhi vetëm disa dekada më parë. Metoda që kemi përdorur që nga kohërat e lashta është në fakt veshja me vaj.
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.
Në procesin e reaksionit të yndyrës në temperaturë të lartë, disa molekula të vogla të paqëndrueshme shndërrohen në blozë dhe largohen, dhe disa molekula të tjera formojnë molekula të mëdha përmes polimerizimit, dehidratimit dhe kondensimit dhe reaksioneve të tjera për t'u ngjitur në enën e hekurit, e cila është origjina e shtresës së filmit të oksidit të zi në enën e hekurit. Dhe hekuri është një katalizator i shkëlqyer për këtë proces.
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
Qëllimi ynë është thjesht të marrim një film oksidi më të fortë dhe më të trashë.
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.
Mund të përdoren edhe vajra të tjerë, por rrjeti i lidhjeve nuk është aq i dendur sa, të themi, vaji i lirit. Dhjami i derrit, të cilin shpesh e përdorim për të zier tenxheren, është thjesht një traditë që është trashëguar dhe nuk është aq i mirë sa vaji i zakonshëm bimor për sa i përket rezultateve praktike.
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.
Gjatë përdorimit të tenxheres prej hekuri, shtresa e vajit do të bëhet natyrshëm gjithnjë e më e trashë. Gërvishtjet e shkaktuara nga gërvishtjet lokale mund të riparohen vetëm me një ose dy enë më shumë. Është në rregull ta përdorni herë pas here për të zier ujë të ziejë ngadalë.
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.
Parandalimi i ndryshkut: Pika kryesore e parandalimit të ndryshkut është rezistenca ndaj ujit. Sigurohuni që ta thani ose thajeni pas çdo përdorimi dhe mos e mbani ujin gjatë natës. Nëse nuk do ta përdorni për një kohë të gjatë, thajeni me një shtresë vaji dhe ruajeni në një vend të freskët dhe të thatë.
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!
