Are all made precisely in the same manner. When the fruit is full ripe, gather it on a dry day: as soon as it is nicely picked, put it into a jar, and cover it down very close.
Set the jar in a saucepan about three parts filled with cold water; put it on a gentle fire, and let it simmer for about half an hour. Take the pan from the fire, and pour the contents of the jar into a jelly-bag: pass the juice through a second time; do not squeeze the bag.
To each pint of juice add a pound and a half of very good lump sugar pounded; when it is dissolved, put it into a preserving-pan; set it on the fire, and boil gently; stirring and skimming it the whole time (about thirty or forty minutes), i. e. till no more scum rises, and it is perfectly clear and fine: pour it while warm into pots; and when cold, cover them with paper wetted in brandy.
Jellies from other fruits are made in the same way, and cannot be preserved in perfection without plenty of good sugar.
Those who wish jelly to turn out very stiff, dissolve isinglass. in a little water, strain through a sieve, and add it in the proportion of half an ounce to a pint of juice, and put it in with the sugar.
The best way is the cheapest. Jellies made with two small a proportion of sugar, require boiling so long; there is much more waste of juice and flavor by evaporation than the due quantity of sugar costs; and they neither look nor taste half so well.
