Peel the apples and cut them into quarters, extracting all the seeds. Then throw them into fresh water, sufficient to half cover, and set them on the fire. When they begin to grow soft, mash them with a wooden spoon; then add the sugar; add the grated rinds of several lemons; mix well, and then set all back upon the fire. Stir the mixture while boiling until of the proper consistency, and then pour into jars or glasses. Allow three and a half pounds of fruit to two pounds of sugar.
