Ingredients

Directions

1. 1

   Preheat oven (electric cooker: 150 °C/circulating air: 125 °C/gas: level 1). Wash the plums, remove the stalks and remove stones. Place the plums, cloves and cinnamon sticks in a high, wide, heavy roasting pan. Stir in 100 g sugar.

2. 2

   Reduce the plum puree in the hot oven for about 4 1⁄2 hours. Sprinkle 75 g sugar every 30 minutes and stir well with a wooden spoon. Then reduce for another 3-4 hours, stirring several times.

3. 3

   Prepare the glasses and lids. Remove the cinnamon sticks. Stir in rum. Pour plum puree immediately into the glasses. Close them and put them on the lid for about 5 minutes. This sterilises the air still present in the jar and creates a vacuum.

4. 4

   Turn glasses over again, let plum jam cool down.
