Prepare onion ginger, pour onion ginger into a bowl, add cooking wine, vinegar, soy sauce and salt, and stir. Rub the seasoning on the chicken legs and marinate for 30 minutes. After 30 minutes, put the drumsticks into the pot, bring them to a boil with high fire and simmer for 30 minutes.

Pressure cooker, also known as pressure cooker and 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, thus accelerating the efficiency of stewing food.

It can be used to heat cooked food to above 100℃. At high altitude, 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 improper operation or defective operation may lead to explosion and personal injury. 1679 was invented by French physicist Papin.

Electric pressure cooker is easy to use, expensive, low working pressure, 50KPa( 150KPa), heat preservation function, and the inner cooker can be disassembled and replaced.

Fish can be stewed intelligently, without water, without automatic power failure, and can be heated and kept warm at intervals. The problem of line aging is not as long as the service life of pressure cooker.

The shell of the electric pressure cooker can keep warm, and the energy efficiency is naturally higher than that of the traditional pressure cooker. Although gas is not expensive, cooking time above 1 hour is obviously not low-carbon.
