Rinse and drain the blueberries, then place them in a large bowl. Using a potato masher or fork, crush the blueberries until they are broken down but still slightly chunky.
Wash and trim the rhubarb stalks, then finely chop them into small pieces. Add the chopped rhubarb to the crushed blueberries.
Mix in the granulated sugar and lemon juice thoroughly. Let the mixture stand for 10 minutes, stirring occasionally to ensure the sugar dissolves and incorporates with the fruit.
In a small saucepan, combine the powdered fruit pectin and water. Bring the mixture to a boil over medium-high heat while stirring constantly. Allow it to boil for 1 minute, then remove it from the heat.
Quickly pour the hot pectin mixture into the fruit mixture. Stir vigorously for 3 minutes, ensuring all ingredients are evenly distributed.
Ladle the jam into clean, freezer-safe containers, leaving about 1/2 inch of space at the top for expansion. Wipe the rims clean and seal tightly with lids.
Allow the jam to sit at room temperature for 24 hours to set. Once set, store the containers in the freezer for up to 1 year or in the refrigerator for up to 3 weeks.
Thaw frozen jam in the refrigerator before use and enjoy the bright, fresh flavors on toast, scones, or mixed into yogurt!
