In a medium saucepan, combine all the ingredients, then heat to a simmer.

Reduce heat to low, cover with a lid, and gently simmer for 45 to 60 minutes while stirring often. While simmering, keep covered, leaving just a tiny space for the steam to escape. Ensure that it simmers slowly. Stir every now and again.

Place the mixture in a blender and blend until smooth.

After allowing it fully cool, put to a medium jar. Refrigerate after fully cooling, then tightly cover.

This jam will keep in the refrigerator for about 6 weeks without being canned.
