If you have an extremely well built pressure cooker you can even fry chicken or other meats in it such as chicken fried steak. Your fried meats have never been as tender and as flavorful. And they take 1/3 the time as normal frying. I will caution you though that your must have an extremely well built pressure cooker and preferably an airvent, frying in a pressure cooker can be very dangerous if done wrong due to explosions or if not properly aspirated or cooled before opening the oil can shoot out and cause fires.
So many have found out the hard way.
