For the peach jam, wash the peaches, remove the pits, cut into small pieces, mix with sugar, cinnamon and rum and put into an unperforated cooking dish. Cook at 100 °C for half an hour.
Let rest for 15 minutes, puree the mass and then immediately pour the still hot mass into jars and seal the peach jam airtight.
Preparation Tip:
Drizzle some high-proof alcohol over the peach jam in the jar, then light and seal immediately. This increases the shelf life of the jam.
