No one likes to eat meat that does not tear apart easily with the chew of your teeth. Thus, meats should be tenderized so that we can enjoy the meat without whine. Over the stove, tenderizing would require specific spices, energy from beating with mallets, and time for meats to become tender. However, pressure cookers can eliminate that problem as the mechanics of its pressure is designed to tender meat to become juicy and tender.
