This easy Mixed Berry Jam with pectin is a thick, spreadable jam! It uses four berries and is the perfect balance of tart and sweet. This recipe can be made in a small batch or scaled into a large batch and it will be perfectly thick every time!
In a medium pot combine strawberries, blueberries, raspberries, blackberries, sugar, lemon juice, and citric acid. Stir to combine.
Cook over medium low until the berries begin releasing their juices and then increase heat to medium. Cook over medium heat until the juices begin to thicken.
In a small bowl whisk pectin and 1 teaspoon sugar.
Once jam has thickened a bit, gradually whisk in the pectin mixture. Whisking it in with the sugar will help prevent clumps.
Boil one minute and then either pour into clean, sanitized canning jars or pour out to cool before storing.
