Rare meat. Grindley and Sprague have suggested, for convenience, that meat with an interior temperature at its center of 60 °C. or below be called rare. Such meats are juicier than meats cooked well done. Nearly all the interior may be a bright red color or only a small portion around the center of the meat may be red. The extent or uniformity of the red color depends upon the cooking temperature. As the heat penetrates the meat the color near the surface becomes gray. If the cooking temperature is high, this gray layer may extend nearly to the center of the meat. If the meat is cooked at a low temperature the gray color extends only a short depth and the color of the interior of the meat is nearly uniform. Thus it can be seen that if different cooking temperatures are used the interior of different pieces of meat cooked to the same inner temperature may vary decidedly in appear- ance. The intensity of the red color may vary with other factors as well as with the cooking temperature. The interior of cooked meat ripened 40 to 60 days is grayer in color than meat that has not been ripened. Veal cooked to the same inner temperature, and with the same cooking temperature, is grayer, and has less red color, than beef. Rare meat also has more of the original meat flavor than well-done meat, for not so much of the fluids and extractives giving flavor to the meat has been lost. Medium well-done meat. Grindley and Sprague have suggested that meat that has reached an inner temperature of 60° to 70°C. be called medium well done. Here the color also varies with the temperature of cooking, the degree to which the meat has been ripened, and in some in- FACTORS AFFECTING THE TIME IN COOKING MEAT 233 stances with the age of the animal and the kind of meat. Rare and medium well-done meats are probably more often associated with the color of the cooked meat. Since the color of the cooked meat varies with different con- ditions, the division into rare, medium well done and well done on the basis of inner temperature of the meat is only an arbitrary one and not always satisfactory. Most people would be agreed that medium well-done meat should not be a deep red or pink, but should show some pink color. Well-done meat. Meat that has a uniform gray color throughout the entire interior of the meat is usually called well done. With veal, this stage of cookery is sometimes reached before or by the time the inner tem- perature of the meat has reached 71°C. This may also be true of beef that has ripened sufficiently. Unripened beef requires a higher temperature than 7l°C. before a uniform gray color is attained, when a low cooking tem- perature is used. But to some persons the term well done is associated with the degree of cookery, that is, the separation of the muscle fibers due to formation of gelatin from the connective tissue. It may also refer to the dryness of the meat and the loss of juices. The meat may be cooked until it reaches a temperature far above 7l°C., often from 80° to 85°C. for roasts and from 95° to 99°C. for braised meat. Factors Affecting the Time Required for Cooking Meat
