1. Stew the steak in the pressure cooker for 15 to 20 minutes.

2. When using a pressure cooker to press steak, you need to boil it over high heat at first, then turn to low heat and cook until done. Remove it from the heat, then put it into the pot with cold water. Bring to a boil over high heat, then add an appropriate amount of seasoning, mix well, and then turn to low heat. Press slowly. If you like it chewier, cook it for 15 minutes. If you like it softer, cook it for about 20 minutes or longer.
