“ If you wish your sweetmeats to look bright and clear, use only the very best loaf-sugar. Fruit may be preserved for family use and for common purposes, in sugar of inferior quality, but it will never have a good appearance, and it is also more liable to spoil.If too small a proportion of sugar is allowed to the fruit, it will certainly not keep well. When this experiment is tried it is generally found to be false economy; as sweetmeats, when they begin to spoil, can only be recovered and made eatable by boiling them over again with additional sugar ”
