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).
Însă, în ceea ce privește tratamentul suprafeței, există o mulțime de categorii diferite. Emailate, pulverizate cu rășină sau vopsea, galvanizate, înnegrite prin oxidare.
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.
Un alt factor de luat în considerare este forma, manopera, calitatea, greutatea și alte condiții nerigide, în funcție de preferințele lor pe linie.
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.
Cea mai directă metodă este acoperirea cu un strat antiaderent. Utilizarea PTFE și a altor materiale ca strat antiaderent datează de doar câteva decenii. Metoda pe care o folosim din cele mai vechi timpuri este, de fapt, placarea cu ulei.
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.
În procesul de reacție la temperatură înaltă a grăsimii, unele molecule mici volatile se transformă în funingine și dispar, iar alte molecule formează molecule mari prin polimerizare, deshidratare, condensare și alte reacții, atașându-se de vasul de fier, care este la originea stratului de peliculă de oxid negru de pe vasul de fier. Fierul este un catalizator excelent pentru acest 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
Scopul nostru este pur și simplu să obținem o peliculă de oxid mai puternică și mai groasă.
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.
Se pot folosi și alte uleiuri, dar rețeaua de legături nu este la fel de densă ca, să zicem, uleiul de in. Untura de porc, pe care o folosim adesea pentru a fierbe oala, este doar o tradiție transmisă în generație și nu este la fel de bună ca uleiul vegetal obișnuit din punct de vedere al rezultatelor practice.
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.
În procesul de utilizare a vasului de fier, pelicula de ulei va deveni în mod natural din ce în ce mai groasă. Zgârieturile cauzate de zgârieturile locale pot fi reparate cu doar una sau două vase în plus. Este în regulă să o folosiți ocazional pentru a fierbe apa la foc mic.
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.
Prevenirea ruginii: Punctul cheie în prevenirea ruginii este impermeabilitatea. Asigurați-vă că îl uscați sau îl uscați după fiecare utilizare și nu îl țineți în apă peste noapte. Dacă nu îl utilizați pentru o perioadă lungă de timp, uscați-l într-un strat de ulei și depozitați-l într-un loc răcoros și uscat.
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!
