To Preserve Black Pear-plums Or Damascenes

Take two Pound of Plums, and cut them in the Seam; then take a Pint

and half of Jelly, made of the same Plum, and three Pound and a half

of Sugar; boil the Jelly and Sugar, and scum it well; put your Plums

in a Pot; pour the Jelly on them scalding hot: When they are almost

cold, heat them again; so do 'till they are tender, and then let

them stand two or three Days, heating them every Day; then boil them

'till they look clear and jelly: Don't boil them too fast.
