Take the walnuts, at the beginning of July, before they are shelled; just scald them, that the skin may rub off, then put them into salt and water, for nine or ten days; shift them every day, and keep them covered from the air: dry them; make your pickle of the white wine vinegar, long pepper, black pepper, and ginger; beat the spice; add the mustard-seed; strew this between every layer of nuts. Pour liquor, boiling hot, upon them, three or four times, or more, if required. Be sure to keep them tied down close.
