Blueberry lime Jam

Wash and drain blueberries. Crush in large bowl with a potato masher or buzz in a food processor to produce the required 4 1/2 cups. In a large pan place berries, lime peel, lime juice and sugar, mixing well. Bring to boil, stirring until the sugar is dissolved, then bring mixture to a full rolling boil. Boil hard for one minute. Remove from the heat and stir in the liquid pectin, stirring a few minutes to cool slightly. Carefully ladle into hot sterilized jars. Leave approx 1/4 inch head space if sealing with paraffin wax. Or seal with jar lids. Yield: approx five 12 ounce jars.
