This is generally made by the large quantity.
Boil down a kettleful of cider to two-thirds the original quantity.
Pare, core, and slice juicy apples, and put as many into the cider as
it will cover. Boil slowly, stirring often with a flat stick, and when
the apples are tender to breaking, take them out with a perforated
skimmer, draining well against the sides of the kettle. Put in a second
supply of apples and stew them soft, as many as the cider will hold.
Take from the fire, pour all together into a tub or large crock; cover
and let it stand twelve hours. Then return to the kettle and boil down,
stirring all the while until it is the consistency of soft soap, and
brown in color. You may spice to taste if you please.
Keep in stone jars in a dry, cool place. It should keep all winter.
