To every pound of damsons allow three-quarters of a pound of pounded loaf sugar; put into jars alternately a layer of damsons, and one of sugar tie them over with bladder or strong paper and put them into an oven after the bread is withdrawn, and let them remain till the oven is cold. The following day strain off the sirup, and boil it till thick. When cold, put the damsons one by one into small jars, and pour over them the sirup, which must cover them. Tie them over with wet bladder.
Prick them with a needle, and boil them with sugar the same proportion as in the receipt to preserve damsons, till the sirup will jelly. Carefully take off all the scum.
