Cranberries are very high in pectin so this jam should be success to everyone!
Recipe makes two by 250ml jars

340g Fresh Cranberries
250g sugar
1 orange
1 cup port
1/2 vanilla pod

Wash cranberries and put in a saucepan over low heat. Grate over the orange rind. Squeeze the orange and add juice to cranberries. Cook slowly for about 5 minutes until some cranberries pop. Split the vanilla pod and scoop out the little seeds add seeds and stick to cranberries. Add sugar and stir once. Keep on low heat until sugar dissolves, taking care that no sugar crystals stick to side of pan(if it does simply brush down with a little water). Turn heat high and bubble mixture for 5 minutes. Transfer to preserving jars and make sure to divide the vanilla pod between both jars for flavor. Seal and turn upside down for 1 minute to sterilize the cap. Will keep in your larder for over 1 year.
