Edward Lambert, The Art of Confectionary
“ Take the largest and fairest Rasberries you can get, and to every Pound of Rasberries take one Pound and a Half of Sugar, clarify it, and boil it till it blows very strong; then put in the Rasberries, and let them boil as fast as possible, strewing a little fine beaten Sugar on them as they boil; when they have had a good Boil, that the Sugar rises all over them, take them from the Fire, and let them settle a little, then give them another Boil, and put to every Pound of Rasberries half a Pint of Currant-Jelly ”
