Original Receipt in 'English Housewifry' by Elizabeth Moxon, 1764 (Moxon 1764)46. BARBERRY DROPS.
When the barberries are full ripe, pull 'em off the stalk, put them in a pot, and boil them in a pan of water till they are soft, then pulp them thro' a hair-sieve, beat and searce the sugar, and mix as much of the searc'd sugar with the pulp, as will make it of the consistance of a light paste; then drop them with a pen-knife on paper (glaz'd with a slight stone) and set them within the air of the fire for an hour, then take them off the paper and keep them dry.
