There is a variety of coffees; but, unlike the teas, they do not owe their difference of flavor or color to the curing, but to the soil and climate in which they grow. Coffee grows on small trees. The fruit is something like the cherry, but there are two seeds in it. The beans are separated by being bruised with a heavy roller, and are then washed and dried. The longer the raw berry is kept the riper and better flavored it becomes. In countries where coffee is grown the leaves are used as much as the berry. Like tea, coffee must be roasted, that the fine flavor shall be developed. There are large establishments for roasting and grinding coffee. The work is done by machinery; and nearly always the grains arc evenly roasted, and just enough to give the right flavor. If the coffee, after roasting, is put in close tin cans, it will retain its best qualities for a long time. It can be ground when needed for use. Many persons think that heating the dry coffee just before making improves the flavor. There are many modes of making coffee, each having its advantages and disadvantages. Some people think that by first wetting the coffee with cold water, and letting it come to a boil, and by then adding the boiling water, more of the strength of the coffee is extracted. When there is not cream for coffee the milk should be boiled, as it makes the coffee richer. As soon as the milk boils up it should be taken off of the stove, since it grows strong and oily by much boiling. To many people it is injurious to drink coffee; but physicians say that, taken without milk, it is harmless. Some element of the coffee combines with the milk to form a leathery coating on the stomach, which impairs digestion. A great many substances are mixed with coffee, when sold, to cheapen it,--chicory, beans, peas, rye, and wheat being the commonest. To obtain it pure, the safest way is to buy it unground, unless you purchase of a strictly honest dealer. Coffee drinkers, as a rule, eat less than other people, though coffee, and also tea, have little direct food value; but they retard the waste of the tissues, and so take the place of food. The sugar and milk used with them give some nutriment.
Boiled Coffee.
The old method of boiling coffee is still practised by at least one-half the housekeepers in this country. The coffee is sometimes boiled with an egg, which makes it perfectly clear, and also enriches it. When an egg is not used a small piece of salt fish skin is boiled with the coffee to clear it.
Directions for making: A small cupful of roasted and ground coffee, one-third Mocha and two-thirds Java; a small egg, shell and all, broken into the pot with the dry coffee. Stir veil with a spoon, and then pour on three pints of boiling water. Let it boil from five to ten minutes, counting from the time it begins to boil. As soon as it has boiled enough, pour in a cupful of cold water, and turn a little of the coffee into a cup, to see that the nozzle of the pot is not filled with grounds. Turn this back, and let the coffee stand a few moments to settle, taking care that it does not boil again. The advantages of boiled coffee are that when the egg is used the yolk gives a very rich flavor, and when the milk or cream is added the coffee has a rich, yellow look, which is pleasing. It has also a peculiar flavor, which many people prefer to the flavor gained by any other process. The disadvantages are that the egg coats the dry coffee, and when the hot water is added the coating becomes hard, and a great deal of the best of the coffee remains in the grounds after boiling. Also, in boiling, much of the fine flavor is lost in the steam that escapes from the pot.
Filtered Coffee.
Another--and really the most economical and the easiest--way of making coffee is by filtering. The French coffee biggin is valuable for this. It consists of two cylindrical tin vessels, one fitting into another, and the bottom of the upper being a fine strainer. Another coarser strainer, with a rod running from the centre, is placed upon this. Then the coffee, which must be finely-ground, is put in, and another strainer is placed at the top of the rod. The boiling water is poured on, and the pot set where it will keep hot, but not boil, until the water has gone through. This will make a clear, strong coffee, with a rich, smooth flavor. The advantage of the two extra strainers is that the one coming next to the fine strainer prevents the grounds from filling up the fine holes, and so the coffee is clear, and made more easily. The upper strainer causes the boiling water to fall on the coffee like rain. In this way it is more evenly distributed, and the fine coffee is not carried through the fine strainer, as it would be if the water were poured directly on the dry coffee. When milk or cream is added to filtered coffee it does not turn a rich yellow, as in the case of that boiled with an egg. A few spoonfuls of this coffee, without sugar or milk, taken after dinner, is said to help digestion.
Vienna Coffee.
A quartet of a cupful of boiled milk. Add three table-spoonfuls of whipped cream, and fill up with filtered coffee.
Café au Lait.
This is simply one pint of filtered coffee added to one pint of milk that has come just to the boiling point.
