If you find that your sweetmeats have become dry and candied, you may liquefy them again by setting the jars in water and making it boil round them.
In preserving fruit whole, it is best to put it first in a thin syrup. If boiled in a thick syrup at the beginning, the juice will be drawn out so as to shrink the fruit.
It is better to boil it but a short time at once, and then to take it out and let it get cold, afterwards returning it to the syrup, than to keep it boiling; too long at a time, which will cause it to break and lose its shape.
Preserving kettles should be rather broad than deep, for the fruit cannot be done equally if it is too much heaped. They should all have covers belonging to them, to put on after the scum has done rising that the flavour of the fruit may be kept in with the steam.
A perforated skimmer pierced all through with holes is a very necessary utensil in making sweetmeats.
The water used for melting the sugar should be very clear; spring or pump water is best, but if you are obliged to use river water, let it first be filtered. Any turbidness or impurity in the water will injure the clearness of the sweetmeats.
If sweetmeats ferment in the jars, boil them over again with additional sugar.
Take eight pounds of the best double-refined loaf-sugar, and break it up or powder it. Have ready the whites of two eggs, beaten to a strong froth. Stir the white of egg gradually into two quarts of very clear spring or pump water. Put the sugar into a porcelain kettle, and mix with it the water and white of egg. While the sugar is melting, stir it frequently; and when it is entirely dissolved, put the kettle over a moderate fire, and let it boil, carefully taking off the scum as it comes to the top, and pouring in a little cold water when you find the syrup rising so as to run over the edge of the kettle. It will be well when it first boils hard to pour in half a pint of cold water to keep down the bubbles so that the scum may appear, and be easily removed. You must not however boil it to candy height, so that the bubbles will look like hard pearls, and the syrup will harden in the spoon and hang from it in strings; for though very thick and clear it must continue liquid. When it is done, let it stand till it gets quite cold; and if you do not want it for immediate use, put it into bottles and seal the corks.
