| More Meat Doneness How do you like your steak cooked?  There is only one right way to interpret the doneness you like---cut the steak in half and check it. That's not practical for a chef to do when cooking in a restaurant.  Steaks may vary in thickness and size, and the grill may vary in temperature.  Also the temperature of the meat in the refrigerator may vary by a few degrees. All of these factors contribute to how much time the steak spends on the grill and the end result.  An experienced chef, after years of practice, can tell the doneness just by feeling the firmness of the steak, rare being soft and spongy and well done being very firm.  The only sure way of determining the doneness is to test the internal temperature with an instant read thermometer inserted precisely into the center of the meat at a 45 degree angle to the flat surface. This will ensure a correct reading of the internal temperature. Don't worry about losing any juices---it's only one small hole you're making. The pictures below represent what each doneness means to a chef.
