Candied Citron Peel recipe
Take peels of citron, immerse them in salted water to eliminate the bitterness, then rinse them in fresh water and lay them out to dry. Cut them into pieces. Take a pound and a quarter of sugar and as much honey and blend them together in a casserole [dast] that one puts on the fire. Skim and throw in the peels. Let it thicken Before taking it off the fire add some ginger, long pepper, Chinese cinnamon, and mastic. If the syrup becomes quite thick it will be very good.
