Ingredients
Quantities are shown as originally provided.
- 4 cups blueberries
- 1/3 cup maple syrup
- Juice from one lemon
Instructions
- 1
Wash and drain blueberries.
- 2
Add blueberries, maple syrup, and lemon juice to a medium pot and bring to a boil over medium heat.
- 3
Use a potato masher or spatula to mash the blueberries and break them open.
- 4
Once the mixture starts to boil, reduce the heat slightly while still maintaining a gentle boil. The jam will be a violet/purple color and there will be foam as it cooks.

Continue to cook for approximately 30 minutes (time can vary), or until mixture has reduced and thickened, reaches 210F/100C, there is no more "foam". The color of the jam will become a dark purplish blue and look glossy. Another way I determine that the jam is done is if running a rubber spatula across the bottom of the pot leaves a "path" for a moment before the jam fills it in.

Transfer the jam to a jar and let cool completely to room temperature before securing lid.

Keep in the refrigerator or freeze.
