84. LEMONS are a citrus fruit raised in tropical regions. They are
shipped to other climates in cases that hold from 180 to 540, depending
on the size of the lemons, 300 to the case being a medium and commonly
used size. Their quality is judged like that of grapefruit; that is, by
their weight, the texture of their skin, and their general color
and shape.
Lemons contain very little sugar, but they are characterized by a large
amount of acid. Because of this fact, their juice is used to season
foods in much the same way as vinegar is used. In fact, their chief
uses are in making desserts and in seasoning such foods as custards,
pudding sauces, etc. However, their juice is also much used in the
making of beverages, such as lemonade and fruit punch.
