I know people that have this with their cornflakes :) Personaly I like them as a snack, but they are great as a quick dessert with custard or ice cream. I pour the prunes into sterilised glass jars, and they keep for months. If you want these as gifts you can easily double the recipe.
- soak prunes in the port overnight.
- next morning combine everything and simmer for about 30 minutes, stirring occasionaly.
- take out vanilla bean. (You can wash it and use it again).
- bottle, or store in the fridge.
