Plum marmalade

Blanch, peel and deseed the plums. Combine the plums, jam sugar and cinnamon sticks in a saucepan and boil for 3-4 minutes, stirring constantly.

Remove the cinnamon sticks and skim off the foam carefully. Stir the marmalade quickly. Leave a few small pieces of plum.

Add the rum to taste and boil for another 2 minutes.

Pour into warm, thoroughly cleaned jars. Seal. Store in a cool place.
