3-Day Marmalade

First day: Cut sour oranges and grapefruit in half and remove the seeds. Cut the pulp and rind in slices. Measure. Add 3 times as much water as fruit. Let the mixture stand.

Second day. Boil the mixture for 20 minutes at a hard boil. Set aside until the next day.

3rd day. Measure the mixture and measure an equal amount of sugar. Boil only the fruit for 20 minutes, then add sugar all at once. Stir. Boil gently for 35 minutes or until a small sample jells on a cold saucer. Seal with paraffin while hot.
