Coffee may be adulterated in a number of ways. Ground coffee is especially easy to adulterate with bread crumbs, bran, and similar materials that have been thoroughly browned. Many of the cheaper coffees are adulterated with chicory, a root that has a flavor similar to that of coffee and gives the beverages with which it is used a reddish-brown color. Chicory is not harmful; in fact, its flavor is sought by some people, particularly the French. The objection to it, as well as to other adulterants, is that it is much cheaper than coffee and the use of it therefore increases the profits of the dealer. The presence of chicory in coffee can be detected by putting a small amount of the ground coffee in a glass of water. If chicory is present, the water will become tinged with red and the chicory will settle to the bottom more quickly than the coffee.
PREPARATION OF COFFEE
25. SELECTION OF COFFEE.--Many varieties of coffee are to be had, but Mocha, Java, and Rio are the ones most used. A single variety, however, is seldom sold alone, because a much better flavor can be obtained from blend coffee, by which is meant two or more kinds of coffee mixed together.
It is usually advisable to buy as good a quality of coffee as can be afforded. The more expensive coffees have better flavor and greater strength than the cheaper grades and consequently need not be used in such great quantity. It is far better to serve this beverage seldom and to have what is served the very best than to serve it so often that a cheap grade must be purchased. For instance, some persons think that they must have coffee for at least two out of three daily meals, but it is usually sufficient if coffee is served once a day, and then for the morning or midday meal rather than for the evening meal.
After deciding on the variety of coffee that is desired, it is well to buy unground beans that are packed in air-tight packages. Upon receiving the coffee in the home, it should be poured into a jar or a can and kept tightly covered.
26. NECESSARY UTENSILS.--Very few utensils are required for coffee making, but they should be of the best material that can be afforded in order that good results may be had. A coffee pot, a coffee percolator, and a drip pot, or coffee biggin, are the utensils most frequently used for the preparation of this beverage.
27. If a COFFEE POT is preferred, it should be one made of material that will withstand the heat of a direct flame. The cheapest coffee pots are made of tin, but they are the least desirable and should be avoided, for the tin, upon coming in contact with the tannic acid contained in coffee, sometimes changes the flavor. Coffee pots made of enamelware are the next highest in price. Then come nickel-plated ones, and, finally, the highest-priced ones, which are made of aluminum. The usual form of plain coffee pot is shown in Fig. 2.
