It is impossible to give a rule which shall at all times apply to the making of fruit jellies, on account of the always variable condition of the fruit. But in general, grapes, cranberries, currants, and similar fruits require a short time, while apples, crab-apples, lemons, and oranges will take from one and a half to three hours. One is therefore obliged to test the jelly at intervals by taking out a little on a saucer to cool. If it becomes firm quickly, the mixture is cooked enough; if not, one may get an idea, from the consistency which it has, what further cooking will be necessary. APPLE JELLY Wash and wipe good tart apples. Cut them in quarters or, better, eighths, but do not pare them. Stew them in half their bulk of water,--that is, if you have four quarts of cut apples, put in two quarts of water,--until the skins as well as the pulp are perfectly soft. No definite time can be given, because that depends upon the kind and ripeness of the fruit. When done, turn them into a jelly-bag and drain until the juice is all out. Measure it, and for each cup add a cup of sugar, one clove, and one square inch of thin lemon-peel. Simmer gently for half an hour, then test it, to see how near the jellying-point it is, by taking out a little into a cool saucer. With some kinds of apples it will be done in that time, with others it will take an hour or more longer. When a little becomes firm on cooling, remove the whole immediately from the fire, skim it, and strain it into jars or tumblers which have been thoroughly washed in soap and water, and have been standing in boiling water for some minutes. When the jelly is cool, pour over the surface a thin coating of melted paraffin, let it harden, then pour in another; for, as the first hardens, it may crack or shrink from the sides and leave spaces where ferments may enter; in other words, the jars need to be made air-tight--not that the air does mischief, but because it contains the organisms which, on entering the jelly, cause by their growth the various fermentative changes known to occur in fruits. The object then will be to exclude all micro-organisms. There are other ways of sealing jelly than by the use of paraffin, as, for instance, with paper soaked in alcohol, or coated with oil; but paraffin, if properly used, is a sure, easy, and economical means.
