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.
