Sloe Plum and Apple Jam

Rinse the sloe plums, remove the stems, cover with water, and simmer under a lid for 5–7 minutes until tender.

Drain the berries through a sieve and press them through to remove the pits.

Peel the apples, core them, dice them, and mix with the strained sloe plum puree.

Add the sugar, bring the mixture to a boil, and simmer for 5 minutes, stirring occasionally.

Let it cool completely and repeat the boiling process two more times, allowing the jam to cool down fully between each batch.

Sterilize the jars and lids just before the final boil.

Bring the jam to a boil a fourth time and cook for 1 minute.
