Coffee

By Charles Skyler

Lemon is a small, evergreen tree that produces flowers and fruits throughout the year, so that a single specimen has blossoms, green fruits and ripe yellow fruits at the same time. The structure of the lemon is best seen in a cross-section. Inside is a juicy pulp divided into as many as 15 sections, usually without seeds.

The pericarp is composed of two layers, a white, spongy inner layer (albedo) and an outer cover or rind (flavedo), coloured yellow when ripe and containing numerous large cells filled with the essential oil of lemon which gives the peel its characteristic smell.

It is obtained by carefully peeling the rind of fully-ripened lemons; this may be dried and then crumbled and stored in air-tight containers for later use.

Otherwise coffee is used to flavour milk, puddings, custards, cakes and ice cream, generally in the form of filtered coffee made with boiling water. The best flavour and aroma, however, is obtained by steeping coarsely ground coffee in fresh cream at room temperature. Though it takes longer this method preserves the finest aromatic substances which would otherwise evaporate.

Lemon peel gives foods a refreshing aroma and is used in pastries, candies and compotes. The essential oil of lemon is obtained for industrial purposes by pressing (prime quality) or distillation (lower quality).

Besides the peel, lemons also provide juice that is a rich source of Vitamin C and can he used in place of vinegar. Its acidity is due to the presence of citric acid so that it can he used even by those who cannot tolerate vinegar. Also its scent is far less penetrating than that of vinegar.
