In a pot over medium-high heat, combine berries and lemon juice. Bring to a boil and cook the berries down until mixture thickens, stir often! Cook for 15 to 20 minutes. While cooking, remove any foam that forms on top.

Add the agave or honey to the berries and stir until well blended. Reduce heat to medium-low; continue to cook the berries down over a soft boil, stirring occasionally, until thickened (coating the back of spoon) and deep red in color, about 15 to 20 minutes. easy way to test is to drop a droplet of mixture onto a cold plate, if it runs it needs more time, if it stays in solid blob form then its ready! The hot jam will thicken even more upon cooling to room temperature.

When done, remove from heat and cool to room temperature. Then, carefully spoon into sterilized jars and place lids on jars. Store jam up to 5 to 7 days in refrigerator.
