After the water boils, skim the foam until there is no dirty foam. Remove the meat. 2. blanched beef, put it in an electric pressure cooker, add half a bowl of water, and then add seasoning. 1 spoon of soy sauce, 2 tablespoons of soy sauce, 2 tablespoons of vinegar, 3 tablespoons of yellow wine, 5 hawthorn, cinnamon, fragrant leaves, pepper and aniseed are put into the seasoning box, one onion is cut into pieces, ginger is sliced, rock sugar, black pepper and salt are mixed.

Pressure cooker, also called pressure cooker, pressure cooker, is a kind of kitchen cooker. The pressure cooker exerts pressure on water through the physical phenomenon that the boiling point of liquid will rise under higher air pressure, so that the water can reach a higher temperature without boiling, so as to speed up the efficiency of stewing food. It can be used to heat the cooked food to above 100℃. In high altitude areas, the pressure cooker can avoid the problem that the boiling point of water decreases and it is difficult to cook food.

Its advantages are time-saving and energy-saving, but its disadvantages are that it may explode and cause injury when it is improperly operated or defective.

Pressure cooker, also called pressure cooker. The advantage of using pressure cooker is not only that the cooking time is short, but also that the cooked food tastes good, especially the meat that is not easy to cook becomes easy to cook and tastes good.

However, at the earliest time, the name of pressure cooker was "Pap Ping Guo", which was invented by a French doctor named dennis Papin. Papin is both a doctor, a physicist and a mechanical engineer. Solid knowledge of physics and mechanical theory is a reliable basis for his invention of pressure cooker.
