Ingredients

Servings: 1
  • 3.5 kg Plums and prunes
  • 8–10 Cloves
  • 5 Cinnamon sticks
  • 100 g (600 g) + 8 x 75 g sugar
  • 3 TABLESPOONS Rum
  • 7 Screw-top jars with twist-off lids (approx. 200 ml each)

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.
