Second Extraction
Return fruit pulp to kettle, add barely enough cold water to cover it, bring slowly to boiling point, stirring to prevent burning on; cook 5 minutes, drain and finish as for first extraction, boiling 5 minutes before adding the sugar.
Third Extraction
Proceed as for second extraction. Oftentimes the juice from second and third extractions may be combined before being made up into jelly. By making three extractions the amount of jelly obtainable from a given amount of fruit may be almost doubled.
