Place the frozen mixed berries in a large saucepan and pour in the water.
Heat the saucepan over medium heat, stirring occasionally, until the berries release their juices and soften (about 5 minutes).
Using a potato masher or the back of a spoon, mash the berries until your desired consistency is achieved. For a smoother jam, blend with an immersion blender.
Add the granulated sugar, lemon juice, and powdered pectin to the mashed berries. Stir well to combine.
Bring the mixture to a rolling boil over medium-high heat, stirring constantly to prevent sticking.
Once boiling, reduce the heat to medium and continue to cook for an additional 10–12 minutes, stirring frequently, until the jam thickens. To test doneness, scoop a small amount of jam onto a chilled plate; if it gels and doesn’t run, it’s ready.
Remove the saucepan from heat and allow the jam to cool for 5 minutes, skimming off any foam with a spoon if necessary.
Ladle the jam into sterilized jars, leaving about 1/4 inch of headspace. Seal with clean lids and bands.
Let the jars cool to room temperature before storing in the refrigerator for up to 3 weeks or processing in a boiling water bath for long-term storage.
