Beef should be aged a few days before cutting. The amount of aging will depend on the amount of fat covering, desired flavor and temperature. Carcasses that have only a thin fat covering should be aged three to five days; those with more fat, five to seven days. Very little tenderization occurs after seven days.
Ask your average paleontologist who is familiar with the phylogeny of vertebrates and they will probably tell you that yes, birds (avians) are dinosaurs. Using proper terminology, birds are avian dinosaurs; other dinosaurs are non-avian dinosaurs, and (strange as it may sound) birds are technically considered reptiles.
Reptiles are cold-blooded. That is, they lack the ability to regulate their metabolic heat (heat derived from the oxidation, or burning, of food and from other processes) for the production of sustained body warmth and a constant body temperature.Cold-bloodedness, however, does not mean that a reptile is necessarily cold.he class Reptilia (living and extinct reptiles) is divided into 6 to 12 subclasses by different authorities. A number of these subclasses are completely extinct. The subclasses contain about 24 orders, but only 4 of these are still represented by living animals.
