Hello, I am happy to answer your questions! Stewing large bones in a pressure cooker takes 15-20 minutes. The temperature reached by the pressure cooker is 100 degrees higher than the boiling point at room temperature, and the time required to stew large bones in a pressure cooker is shorter than that of an ordinary iron pot. Moreover, the high pressure and short time required to stew large bones in a pressure cooker will not destroy the nutrition of the food. Stewing large bones in a pressure cooker consumes less water, so you don’t need to add too much water.

The pressure cooker, also called a pressure cooker, is a kitchen pot invented by a French doctor named Denis Papin. A pressure cooker applies pressure to the water through the physical phenomenon that the boiling point of liquid increases under higher pressure, allowing the water to reach a higher temperature without boiling, thereby speeding up the efficiency of stewing food. I hope my answer is helpful to you, welcome to adopt it!
