When we cook delicious food, we pay great attention to the selection of pot. It should be that only the right pot can cook delicious food, but many people often get confused about the choice of pot. Do you know how to choose iron pot? Is it better to choose cooked iron pot or pig iron pot? Let's have a look
1. Wrought iron has good ductility and high toughness. It can forge and press the pot relatively thin. The heat transfer of the wrought iron pot is fast, while the pig iron is relatively brittle. The cast process can produce the cast iron pot, which can not be produced relatively thin. The heat transfer of the pig iron pot is not as fast as that of the cooked iron pot. Therefore, from the perspective of saving fuel and electricity such as firewood and gas, the cooked iron pot is more suitable than the pig iron pot.
2. For the iron pot used for food frying, raw iron pot should be selected. The heat transfer of pig iron pan is generally slower than that of cooked iron pan, and the heat dissipation rate is higher than that of cooked iron pan. Therefore, when frying food, pig iron pan is less easy to paste than cooked iron pan, and the oil temperature is not easy to be too high. Too high oil temperature will lead to food coking.
3. The surface of the pig iron pot has low smoothness and fine cracks. If you fry food for a long time, a layer of carbide film (pot scale) and oil film will be formed on the surface, which can prevent the oil temperature from being too high on the one hand and rust on the other hand. The surface of cooked iron pot is smooth. Unless the pot is fried, it is generally difficult to form pot scale
Raw iron pot is melted and cast with gray iron, while cooked iron pot is forged with cooked iron. The difference in manufacture leads to the different functions of the two pots. We can't comment on which is good or bad. It is mainly evaluated according to the needs of cooking. It's good to fry some food in a raw pot and cook some food in a raw pot. Each of the two pots has its own advantages. We can buy both pots according to the needs of the family.
