Smash your berries lightly using the back of a wooden spoon or potato masher.

Transfer the berries to a large pot and stir in both the lemon juice and pectin. Bring to a boil stirring consistently to avoid any burning.

Stir in the sugar and return to a boil. Allow to cook for 3 minutes making sure to continue stirring.

Place into sterilized jars and follow proper canning instructions.
