The slate of fried steak is granite.

the specific heat capacity of granite is 92 j/(kg℃), and that of cast iron is 46 j/(kg℃). Granite with the same weight can store twice as much heat energy as cast iron.

Therefore, the thermal insulation effect of stone tableware and kitchenware (including ceramics and salt plates) is better than that of cast iron. Stone and ceramics have poor thermal conductivity, which is not as good as cast iron. If the steak is fried with slate, it will take longer to reach the required high temperature when it is put on the fire because of its poor thermal conductivity.

However, after the steak is put on, the temperature of the slate next to the steak drops rapidly, while the heat in other parts of the slate flows slowly in the direction of the steak, so the "fast and high temperature" conditions required for the steak to be cooked outside and tender inside are insufficient.

nutritional value

beef contains the most, highest and richest elements needed by human body. Including: protein, blood iron, vitamins, zinc, phosphorus and a variety of amino acids. It is impossible for the human body to get all the nutrients it needs when it absorbs the nutrients of various foods, but it is the most direct and complete intake from beef.

beef food contains these eight essential amino acids which are 1% absorbed by human body. The nutrition of any animal or plant can't be compared with beef. Therefore, it is said that eating a piece of beef is worth a day's nutrition.

Basic information:

Fried steak is a simple dish. The main ingredient is steak, and the main cooking technology is frying. Fried steak belongs to western food, usually served with red wine. Simple steaks can also be cooked at home, and turning over every 15 seconds can keep the surface high and the internal temperature not too high, so as to preserve the gravy.

Although the effect of frying steak with slate is very good, it is also a good choice to put the fried steak on a slightly heated slate for heat preservation. The heat preservation effect is better than that of iron plate. I believe that friends who have eaten bibimbap, casserole and clay pot rice will have an experience.
