Blackberry Jam.--For this it is necessary that the fruit should be quite ripe and perfectly dry when gathered. After picking from the stalks, weigh it, and allow ¾ lb. crushed white preserving sugar to every lb. of fruit. Set them together over a slow fire, stirring with a wooden or silver spoon to prevent burning at first, before the juice begins to run from the berries. The stirring must be almost constant during the whole process, as for any other sort of jam. After coming to the boil, it will be about ½ hour before it jellies, which must be ascertained by putting a very little from time to time on a cool plate. Some people very carefully take off the scum as it rises, but it is not really necessary; if constantly stirred, it will all disappear in the process of boiling, avoiding the waste caused by skimming, while the jam itself keeps equally well. When done, pour it off into jars, taking care that they are quite dry; let them stand till next day, cover the jars with paper, and put them by to keep in a cool, dry place. Another way is to mix ¼ lb. any good cooking apples, weighed after paring and cutting up, to every lb. blackberries; the sharper the kind of apple the better, but they must be ripe. More sugar is required when done in this way, 1¾ lb. sugar to every 2 lb. fruit. The grated rind and strained juice of lemons are also used with blackberries instead of apples, the larger proportion of sugar being allowed, and one lemon (small) to every 2 lb. berries. Some people object very much to the small seeds in this jam. These may be avoided by rubbing the fruit through a sieve as soon as it is sufficiently cooked to admit of it; it must then be put back into the preserving pan to boil till it sets. In this way, supposing the jam to be made of blackberries alone, half its own weight of sugar will be enough when weighing the uncooked fruit, as so much is afterwards lost by removing the seeds. Blackberry Jelly.--(_a_) Put the fruit in the oven, and press it through canvas when tender. Allow rather more than ¾ lb. lump sugar to 1 lb. fruit syrup, and boil ¾ hour. This jelly is much improved by using equal quantities of bullaces and blackberries. The acid flavour of the bullace takes away the flatness of the blackberry. Put the jelly into moulds and cover with papers in the usual way. It is more likely to turn out well after being kept a month or two than at first. (_b_) Boil together a quantity of apples cut small and blackberries that are thoroughly ripe, in the proportion of 1 lb. blackberries to ½ lb. apples. When boiled quite soft and pulpy, strain through a hair sieve and reboil, with ½ lb. loaf sugar to each pint juice, about ½ hour. ¼ pint water to every 4 lb. fruit may be boiled with it to advantage.
