Be certain nuts are not over-ripe. Prick walnuts deeply with silver fork in 2 or 3 places. Soak in brine for 3 days. Take from brine and place on tray, put out in sun, moving them occasionally. Slowly they will turn black. This takes 2-3 days (if very hot 24 hours may suffice). When quite black pack into jars and cover with spiced vinegar. Tie down and mature for at least 1 month before use.
