Green Plum Jam.
Take the great white plums before they begin to turn, when they are at their full growth, and to every pound of plums allow three quarters of a pound of fine sugar. Pare and throw the plums into water, to keep their colour; let your sugar be very finely pounded; cut your plums into slices, and strew the sugar over them. You must first take them out of the water, and put them over a moderate fire, and boil them till they are clear and will jelly. You may put in a few of the stones, if you like them.
