Put into a small iron omelet-pan half a pound of granulated sugar, and place on a slow stove to burn thoroughly for thirty minutes. Remove the pan to the table to cool slightly for five minutes, and then add half a pint of boiling water, mixing well with an iron spoon. Replace the pan on the stove, and boil for five minutes, stirring continually; then strain the sugar through a sieve into a vessel, and put in a cold place to cool thoroughly. Pour it into a bottle, and use when required. Burned sugar prepared this way will keep in perfect condition for several weeks.
