Place all the ingredients in a large saucepan and heat over medium high heat.
Use a stick blender to puree the jam, you may need to do it a couple times.
Let the jam come to a boil, stir frequently.
As the water boils off you'll notice the jam will thicken up and take on a sheen. The spoon will leave a trail as you stir. It should be thick but not stiff.
Allow to cool and transfer to a clean jar.
Store in the refrigerator. Large batches can be frozen as well. Long term storage in the pantry requires a water bath.
