GATHER your elder-berries when they are full ripe, pick them clean from the stalks, put them in large stew pots, and tie a paper over them, put them in a moderate oven, let them stand two hours, then take them out, and put them in a thin coarse cloth and squeeze out all the juice you can get, then put eight quarts into a well-tinned copper, set it over a slow fire, let it boil till it be reduced to one quart, when it grows near done, keep stirring it, to prevent its burning to the bottom, then put it into potting pots, let it stand two or three days in the sun, then dip a paper in sweet oil the size of your pot, and lay it on, tie it down with a bladder, and keep it in a very dry place for use.
