Sour Orange Preserve Recipe

Grate off the rind, cut the orange into two parts, and remove the pulp. Weigh the peel, place it in a large stone pot, and cover with brine made of three gallons of water and a quart of salt. Let it stand twenty-four hours, and drain off the brine. Again cover the peel with brine made of the same quantity of water and half as much salt as was first used, and let it stand another day. Drain, cover with clear cold water, and let it stand a third day. Drain again, and put in a boiler and cover with fresh cold water. Let it come to a boil, and boil fifteen minutes; then take out and drain. Make a syrup of three quarts of sugar and one of water, for every six pounds of peel. When the syrup is clear, drop in the peel and boil until it is clear and tender--perhaps four hours of slow boiling. Great care must be taken that it is not scorched. It must be stirred every fifteen minutes. The sugar may be either white or brown. The orange used is not the common orange, but the wild, sour fruit, found in Florida. The pulp may be used for marmalade.
