26. In the preparation of meat, there is always some waste, and as waste
is a factor that has much to do with the increasing of costs, it should
be taken into consideration each time a piece of meat is purchased. If
there is time for some experimenting, it makes an interesting study to
weigh the meat before and after preparation, for then the amount of
shrinkage in cookery, as well as the waste in bone, skin, and other
inedible material, can be determined.
An actual experiment made with a 4-pound chicken showed that there was
a loss of 2-3/4 pounds; that is, the weight of the edible meat after
deducting the waste was only 1-1/4 pounds. The following shows how this
weight was determined:
POUNDS
Weight of chicken, including head, feet, and entrails 4
Weight of head, feet, and entrails 1-1/4
Weight of bones after cooking 7/8
Weight of skin after cooking 1/4
Shrinkage in cooking 3/8
-----
Total amount of waste 2-3/4
-----
Actual weight of edible meat 1-1/4
It will readily be seen that chicken at 40 cents a pound would make the
cost per pound of edible meat amount to exactly $1.
