01 -
Place a small plate in the freezer to test the jam's setting point later.
02 -
Wash and sterilize your jam jars.
03 -
Wash the fruits well. Do not peel them, but remove the cores from the plums and pears. Cut the fruits into large chunks and place them into a large jam pot.
04 -
Pour the sugar over the fruits and mix well.
05 -
Bring the fruits and sugar to a rolling boil, adding the star anise, cinnamon sticks, and cardamom pods (smash open the cardamom pods to release the aroma).
06 -
Reduce the heat and simmer on low for about 30 minutes, stirring occasionally, until the jam is set (jam setting temperature is 105°C/220°F).
07 -
Test the jam's readiness by placing a drop of the hot jam onto the frozen plate; it should set quickly without running.
08 -
Once the jam is set, remove the spices and use a hand blender to mash the jam until smooth or semi-smooth, depending on your preference.
09 -
Pour the jam into clean, sterilized jars, filling them up to the rim.
10 -
Add a drop or two of rum or whiskey into the jar lids for extra germ protection to prolong the shelf life.
11 -
Close the jars tightly and quickly turn them upside down while still hot to create a vacuum, preventing mold. Leave the jars upside down for about 24 hours.
12 -
Label the jam with the name and date. Store in a cool, dry place, and refrigerate once opened.
