Soak two pounds dried apricots for one or two days in cold water to barely cover. Add four pounds peeled, cored, and sliced apple. Cover closely, and cook in oven until soft. Add about three-fourths its bulk of dark corn syrup and sugar mixed, and half a teaspoon salt. Cook until thick and uniform in color, adding more syrup or brown sugar if not sweet enough. One seeded and chopped lemon may be added if desired.
