Chapter 61: Fried Pork Steak on Slate
Fried steak is a very old cooking method, second only to grilling.
This cooking method has also spread to modern society, such as the Tianban grilled fish and grilled tofu in Chinese cuisine, and the fried steak in Western cuisine. Although the actual cooking methods are very different, the basic operations are similar.
The tool for frying steak is usually an iron plate.
This is because the iron plate is resistant to high temperatures and easy to make, and it can release iron during the cooking process to help replenish the body's iron ions.
You should know that about 70% of the iron in the human body exists in the hemoglobin of circulating red blood cells. The reason why blood appears red is because it contains iron.
If the body lacks iron, the most direct result will be iron deficiency anemia, and the way to treat this anemia is naturally to supplement iron.
Therefore, supplementing iron is, in a sense, equivalent to replenishing blood.
However, considering Xia Tian's current situation, iron smelting is still a fantasy, so she had to settle for the next best thing - frying the steak on a stone slab.
Slate itself is also a very natural cooking ingredient that can preserve the flavor of food to the greatest extent. In the 21st century, some restaurants that pursue retro cooking will choose slate.
The choice of stone is also very particular.
On Earth, rocks are divided into igneous rocks, sedimentary rocks and metamorphic rocks according to the different ways they are formed.
Among them, sedimentary rocks have the lowest hardness, and because they are formed by the deposition of various trace elements, they are also easily corroded, not resistant to high temperatures, and easily become brittle.
For example, limestone is mainly composed of calcium carbonate, which is exactly the same as the main component of river shells, and neither can withstand high temperatures.
The main component of igneous rock is underground magma. Its various properties are relatively stable, and its ability to withstand high temperatures is needless to say. It is the best choice for making fried steaks.
However, most of the time, the lava rocks formed during volcanic eruptions are very irregular in shape, and it is almost impossible to find one shaped like a baking tray, which requires extra time to polish.
The only thing left is metamorphic rock.
Metamorphic rocks are sedimentary rocks that are squeezed and deformed in the strata, and chemical reactions occur between the various substances inside, eventually forming a new type of rock - such as marble.
Metamorphic rocks themselves are very hard, and the cracks in the rocks are very small, so the trace elements inside will not escape. After being baked by high-temperature fire, they are not as fragile as sedimentary rocks. However, they have one disadvantage - they are difficult to find.
Because the formation of metamorphic rocks mainly depends on the pressure of the strata, it will take many years to find them on the surface.
Coincidentally, Xia Tian found a lot of this kind of stone by the river, and they were all cut very neatly.
Although she didn't know the origin of these stones and couldn't identify the specific rock species, it didn't prevent her from finding a small piece to fry the steak - it was more than enough.
The girl cleaned the slate she found, built a simple rack with branches, and placed the slate on it.
The heat used for frying steaks and grilling meat is the same. At the beginning, use high heat to lock in the meat juice inside, and then switch to low heat and heat slowly to denature the protein inside. This is to ensure that the outside is crispy and the inside is tender and not undercooked.
The steak made a sizzling sound on the stone slab. Compared with roasting it over fire, this slow frying method really whetted everyone's appetite.
