TO PRESERVE PLUMS
To every pound of fruit allow three-quarters of a pound of sugar. Divide the plums, take out the stones, and put the fruit on a dish with pounded sugar strewed over; the next day put them into a preserving pan and let them simmer gently by the side of the fire for about thirty minutes, then boil them quickly; removing the scum as it rises, and keep them constantly stirred, or the jam will stick to the bottom of the pan. Crack the stones and add the kernels to the preserve when it boils.
